Several security related problems have been discovered in Mozilla Firefox. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities:
Web pages with extremely long titles cause subsequent launches of the browser to appear to "hang" for up to a few minutes, or even crash if the computer has insufficient memory. [MFSA-2006-03]
The function allocation code allows attackers to cause a denial of service and possibly execute arbitrary code. [MFSA-2006-01]
An anonymous researcher for TippingPoint and the Zero Day Initiative reported that an invalid and nonsensical ordering of table-related tags can be exploited to execute arbitrary code. [MFSA-2006-27]
A particular sequence of HTML tags can cause memory corruption that can be exploited to execute arbitrary code. [MFSA-2006-18]
Georgi Guninski reported two variants of using scripts in an XBL control to gain chrome privileges when the page is viewed under "Print Preview". [MFSA-2006-25]
"shutdown" discovered that the crypto.generateCRMFRequest method can be used to run arbitrary code with the privilege of the user running the browser, which could enable an attacker to install malware. [MFSA-2006-24]
Claus JĂ¸rgensen reported that a text input box can be pre-filled with a filename and then turned into a file-upload control, allowing a malicious website to steal any local file whose name they can guess. [MFSA-2006-23]
An anonymous researcher for TippingPoint and the Zero Day Initiative discovered an integer overflow triggered by the CSS letter-spacing property, which could be exploited to execute arbitrary code. [MFSA-2006-22]
"moz_bug_r_a4" discovered that some internal functions return prototypes instead of objects, which allows remote attackers to conduct cross-site scripting attacks. [MFSA-2006-19]
"shutdown" discovered that it is possible to bypass same-origin protections, allowing a malicious site to inject script into content from another site, which could allow the malicious page to steal information such as cookies or passwords from the other site, or perform transactions on the user's behalf if the user were already logged in. [MFSA-2006-17]
It is possible to trick users into downloading and saving an executable file via an image that is overlaid by a transparent image link that points to the executable. [MFSA-2006-13]
An unspecified vulnerability allows remote attackers to cause a denial of service. [MFSA-2006-11]
Certain Cascading Style Sheets (CSS) can cause an out-of-bounds array write and buffer overflow that could lead to a denial of service and the possible execution of arbitrary code. [MFSA-2006-11]
It is possible for remote attackers to spoof secure site indicators such as the locked icon by opening the trusted site in a popup window, then changing the location to a malicious site. [MFSA-2006-12]
A regression fix that could lead to memory corruption allows remote attackers to cause a denial of service and possibly execute arbitrary code. [MFSA-2006-11]
For the stable distribution (sarge) these problems have been fixed in version 1.0.4-2sarge6.
For the unstable distribution (sid) these problems have been fixed in version 1.5.dfsg+184.108.40.206-2.
We recommend that you upgrade your Mozilla Firefox packages.
