Description Josh Bressers 2006-04-13 03:59:52 UTC 
Crashes with evidence of memory corruption (CVE-2006-1738, CVE-2006-1739)


As part of the Firefox 1.5 release we fixed several crash bugs to improve
the stability of the product. Some of these crashes showed evidence of
memory corruption that we presume could be exploited to run arbitrary code
and have been applied to the Firefox 1.0.x and Mozilla Suite 1.7.x releases

While  fixing  an  unexploitable  recursion-induced crash Bernd Mielke
discovered that the CSS border-rendering code could potentially write past
the end of an array.

Alden  D'Souza  reported a crash when using an extremely large regular
expression in JavaScript. This was tracked down to a 16-bit integer overflow
that could potentially cause the browser to interpret attacker supplied data
as JavaScript bytecode.

Martijn   Wargers  fixed  two  potentially  exploitable  crashes  when
programmatically changing the -moz-grid and -moz-grid-group display styles.

Note:  Thunderbird shares the browser engine with Firefox and could be
vulnerable if JavaScript were to be enabled in mail. This is not the default
setting and we strongly discourage users from running JavaScript in mail.

CVE-2006-1737 bug 280769
CVE-2006-1738 bugs 311710, 313173
CVE-2006-1739 bug 265736

Workaround

Upgrade to the fixed versions. Do not enable JavaScript in Thunderbird or
the mail portions of SeaMonkey and the Mozilla Suite.
