| 94 | Downloading link deletes files | high / high | dataloss |
Firefox simplifies the task of saving files by automatically using a
filename based on the original link. A specific link format triggers
a bug in this feature and can cause the deletion of files in the
download directory. An attacker would need to convince a victim to
click the "Save" button to download a file from their site. Workaround: Cancel unexpected file save prompts and any from untrusted sites. When saving files, right-click on the link and select "Save link as" from the context menu. |

| # | Title | Severity / Risk | Type | Description | Reported by | Date Fixed |
|---|---|---|---|---|---|---|
| 93 | "Send page" heap overrun (258005) | critical / moderate | remote execution | The "send page" function can overrun the heap on very long links. With compelling content that people will want to forward to all their friends and the right link this could be used to execute arbitrary code. | Georgi Guninski | 2004-09-07 |
| 92 | javascript clipboard access (257523) | moderate / high | clipboard leak | Untrusted javascript code can read and write to the clipboard, stealing any sensitive data the user might have copied. Workaround: disable javascript | Wladimir Palant | 2004-09-01 |
| 91 | Privilege request confusion (253942) | critical / low | remote execution | Signed scripts requesting enhanced abilities could construct the request in a way that led to a confusing grant dialog, possibly fooling the user into thinking the privilege requested was inconsequential while actually obtaining explicit permission to run and install software. Workaround: Never grant enhanced abilities of any kind to untrusted web pages. | Jesse Ruderman | 2004-09-01 |
| 90 | Buffer overflow when displaying VCard (257314) | critical / high | remote execution | A stack buffer overrun in VCard display routines could be exploited to run arbitrary code supplied by the attacker. Workaround: Disable in-line display of attachments, don't open VCard attachments. | Georgi Guninski | 2004-08-30 |
| 89 | BMP integer overflow (255067) | critical / high | heap overrun | extremely wide BMP images trigger an integer overflow, leading to heap overruns that are potentially exploitable to run arbitrary code. Workaround: Disable images. | Gael Delalleau | 2004-08-27 |
| 88 | javascript: link dragging (250862) | critical / moderate | cross-domain scripting, possibly remote execution | javascript; links dragged onto another frame or page allows an attacker to steal or modify sensitive information from other sites. The user could be convinced to drag obscurred links in the context of a game or even a fake scrollbar. If the user could be convinced to drag two links in sequence into a separate window (not frame) the attacker would be able to run arbitrary programs. | Jesse Ruderman | 2004-08-26 |
| 87 | non-ascii hostname heap overrun (256316) | critical / high | remote execution | A link with a non-ascii hostname can cause a heap buffer overrun that could potentially be exploited to run arbitrary programs. | Mats Palmgren, Gael Delalleau | 2004-08-24 |
| 86 | Malicious POP3 server III (245066, 226669) | critical / moderate | remote execution | Responses from a malicious POP3 mail server can trigger heap overruns that can be exploited to run arbitrary code. | Gael Delalleau | 2004-08-17 |
| 85 | Wrong file permissions after installing on Linux (231083, 235781) | moderate / low | local exploit | The Linux installers could create files world readable and writable, allowing another local user to replace them with malicious versions. Workaround: chmod the installed files | Daniel Koukola, Andrew Schultz | 2004-08-16 |
| 84 | Wrong file permissions in linux archive (254303) | moderate / low | local exploit | File permissions and owner were set wrong in the Linux install .tar.gz archives. If unpacked with an option to ignore the user's umask setting (or with a permissive umask) the resulting files could be secretly replaced with malicious versions by any other user on the system. Workaround: chmod and chown the files after unpacking. | Harald Milz | 2004-08-16 |

| 83 | buffer and integer overflows in libpng (251381) | critical / high | remote execution | Multiple flaws in libpng were announced, the worst of which could lead to remote code execution via buffer overflow. CAN-2004-0597, CAN-2004-0598, CAN-2004-0599 | Chris Evans | 2004-08-03 |
| 82 | lock icon and certificate spoof with onunload document.write (253121) | moderate / moderate | spoof | The lock icon and certificate from a previous secure site can persist if a page is re-written using an onunload handler. Combined with redirects this could be used to spoof secure sites. The location bar, if shown, displays the true URL. CAN-2004-0763 | Emmanouel Kellinis | 2004-07-27 |
| 81 | Malicious certificates can permanently break HTTPS/SSL (249004) | critical / high | persistent DOS | Malicious email certificates could mask built-in Certificate Authority (CA) certificates. Once imported anything signed by the masked CA would not validate, which could be used to permanently block all SSL (https:) sites with certs issued by that CA.

| 80 | Windows shell: protocol handler (250180) | critical / high | remote execution | shell: URLs were passed to windows for handling which could result in launching programs. This could theoretically be combined with an unpatched exploit in some default windows filetype handler to run arbitrary code | Keith McCanless | 2004-07-07 |
| # | Title | Severity / Risk | Type | Description | Reported by | Date Fixed |
|---|---|---|---|---|---|---|
| 79 | Spoof contents of framed site (246448) | moderate / moderate | spoof | The contents of a frames within a document could be replaced by an attacker with a reference to that window, while leaving the address in the location bar. On a secure site the lock icon would change to broken, but otherwise it could be a successful spoof. | Jesse Ruderman | 2004-06-16 |
| 78 | security dialog popup (162020) | critical / high | remote code execution | An attacker who could lure users into clicking in particular places, or typing specific text, could cause a security permission or software installation dialog to pop up under the user's mouse click, clicking on the grant (or install) button. | Jesse Ruderman | 2004-06-05 |
| 77 | Untrusted content displayed with "chrome" flag (244965) | moderate / low | spoof | Untrusted web content can open windows with the "chrome" style. This suppresses the normal browser frame and makes spoofed dialogs easy (such as the master password dialog). Affects Mozilla 1.6 through 1.7rc2. | James Ross | 2004-06-02 |
| 76 | POP3 mail server heap overrun (229374) | critical / low | heap overrun | A variant of bug 157644 (see #27 below), malicious POP server could overwrite memory and execute arbitrary code. | zen parse | 2004-05-29 |
| 75 | Mac remote code execution via help: and disk: (243699) | critical / high | remote code execution |
lixlpixel reported vulnerabilities in the help: and disk: URI schemes
in some versions of Mac OS X. Web content could access those schemes
through Mozilla. Workaround: install the latest OS patches. |
Mike Calmus | 2004-05-17 |
| 74 | PNG out-of-bounds read (242915) | minor / low | DOS | The libpng project announced a bug that could be exploited as a denial of service attack. See CAN-2004-0421 | Glenn Randers-Pehrson | 2004-05-07 |
| 73 | automatic file upload (241924) | high / moderate | file access |
Regression in Mozilla 1.7-beta only: file upload control value can be
pre-filled using document.write() and innerHTML, allowing attacker to
programmatically submit the form and capture a file at a known location.
Workaround: disable Javascript |
Met - Martin Hassman | 2004-04-28 |
| 72 | SSL Certificate Spoof (240053) | high / high | spoof | A malicious page can use redirects to turn on the SSL lock icon and appear secure. This could be used to further phishing scams. | Tolga Tarhan | 2004-04-10 |
| 71 | Stealing secure HTTP Auth passwords via DNS spoof (226278) | high / low | password theft | HTTP auth passwords were cached by site and port but did not store whether the protocol used was secure (SSL) or not. An attacker who could spoof your DNS could wait until you authenticate to a secure site then redirect a later connection to that site and port during that session to a non-SSL machine under their control, thus stealing the secure password. | Christopher Nebergall | 2004-04-07 |
| 70 | non-FQDN cert name matching is insecure (234058) | minor / low | spoof | A non-FQDN URI hostname can match part of a cert name w/out a warning dialog. Could be used for spoofing if an attacker had control of machines on your default DNS search path. | Tim Dierks | 2004-04-07 |
| 69 | remote access to local files through Liveconnect (239122) | high / high | remote reading | Mozilla 1.7beta allowed remote web pages to read local files in known locations using Liveconnect (requires Java; 1.7alpha and earlier are safe) | Darin Fisher | 2004-04-05 |
| 68 | redefine focus()/blur() on another window (86028) | minor / low | DOS | Attacker can replace some functions on windows he opened. Replaced functions run in the attacker's domain so can't steal data, but could interfere with the operation of the other window. | Jesse Ruderman | 2004-03-25 |
| 67 | SOAPParameter overflow (236618) | critical / high | remote code execution |
An integer overflow passing a large js array to the SOAPParameter
constructor results in a controlled overwriting of the heap, which
can be exploited to run arbitary code of the attacker's choice.
Workaround: disable Javascript |
zen parse / iDEFENSE | 2004-03-08 |
| 66 | drag into file upload control (206859) | high / low | file access | A clever attacker might be able to trick a user into dragging disguised text into an obscured file upload control, resulting in the capture of a user's file at a known location. | Jesse Ruderman | 2004-02-11 |

| 65 | %00 status bar spoof (228176) | minor / low | spoof | %00 in an href truncates the status bar display when you mouse over the link. This could be used to further phishing scams in mail where Javascript is disabled and the status bar might be trusted more than in normal web content. | Secunia | 2004-01-06 |
| 64 | Cross-domain exploit on zombie document with event handlers (227417) | moderate / low | same-origin violation | During page transition it was possible to run event handlers from the old page in the context of the new page. This has been demonstrated to allow cookie stealing, and potentially any sensitive account information displayed by the new site. | Andreas Sandblad | 2003-12-03 |
