Severity: Normal Title: Mozilla Suite, Mozilla Firefox: Buffer overflow Date: September 18, 2005 Bugs: #105396 ID: 200509-11
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
Mozilla Suite and Firefox are vulnerable to a buffer overflow that might be exploited to execute arbitrary code.
Background ==========
The Mozilla Suite is a popular all-in-one web browser that includes a mail and news reader. Mozilla Firefox is the next-generation browser from the Mozilla project. They both support Internationalized Domain Names (IDN), which are domain names represented by local language characters.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/mozilla-firefox <= 1.0.6-r6 >= 1.0.6-r7 2 www-client/mozilla <= 1.7.11-r2 >= 1.7.11-r3 3 www-client/mozilla-firefox-bin <= 1.0.6-r2 Vulnerable! 4 www-client/mozilla-bin <= 1.7.11 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers. ------------------------------------------------------------------- 4 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
The Mozilla Suite and Firefox are both vulnerable to a buffer overflow while processing hostnames containing multiple hyphens. Note that browsers that have disabled IDN support are immune to this flaw.
Impact ======
A remote attacker could setup a malicious site and entice a victim to visit it, triggering the buffer overflow and potentially resulting in the execution of arbitrary code with the victim's privileges.
Workaround ==========
You can disable the IDN support by opening the "about:config" page in the browser and manually toggling the "network.IDN" property to "false". Alternatively, you can install a security patch by following the patching instructions given in References.
Resolution ==========
All Mozilla Firefox users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.6-r7"
All Mozilla Suite users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-1.7.11-r3"
There are no fixed Mozilla Firefox or Mozilla Suite binaries yet. Users of the mozilla-bin or mozilla-firefox-bin packages should either switch to the source-based versions or apply the workaround.
