Version Summary:Red Hat has released an additional security advisory and updated packages to address the multiple Mozilla products HTML editor use-after-free vulnerability.
 
 
Description
Multiple Mozilla products contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code.

The vulnerability exists because the affected software does not perform sufficient sanitization on user-supplied input. An unauthenticated, remote attacker could exploit the vulnerability by convincing the targeted user to visit a malicious website that contains malicious HTML content. Processing the malicious content could cause a use-after-free condition within the HTML editor. Successful exploitation could allow an attacker the ability to execute arbitrary code in the security context of the affected application.

Mozilla has confirmed this vulnerability and released updated software.
 
Warning Indicators
The following Mozilla products are vulnerable:
  • Firefox versions prior to 19.0.2
  • Firefox ESR versions prior to 17.0.4
  • Thunderbird versions prior to 17.0.4
  • Thunderbird ESR versions prior to 17.0.4
  • SeaMonkey versions prior to 2.16.1
 
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.

At the time this alert was first published, updated software versions of SeaMonkey and Thunderbird were unavailable on the vendor's website.

Impact
