Multiple Mozilla products contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system. Updates are available.
Description
Multiple Mozilla products contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to improper handling of certain web pages by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to open a crafted web page. Processing the web page could cause an error, allowing the attacker to execute arbitrary code on the system.
Mozilla has confirmed this vulnerability and released updated software.
Warning Indicators
The following Mozilla products are vulnerable:
Firefox versions prior to 17.0
Thunderbird versions prior to 17.0
SeaMonkey versions prior to 2.14
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
Vendor Announcements
Mozilla has released a security advisory at the following link: MFSA 2012-94
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted system with the privileges of the user. If the user holds elevated privileges, the attacker could completely compromise the system.
Technical Information
The vulnerability is due to a buffer overflow in the affected software while processing SVG text on a path in Cascading Style Sheet (CSS) properties in web pages.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to open a web page that contains malicious SVG text in CSS. The processing of the web page could cause a buffer overflow, corrupting memory. The attacker could use the memory corruption to execute arbitrary code on the system.
