Effective 2019 Sep 15, Cisco will no longer publish non-Cisco product alerts. Cisco will continue to publish Security Advisories to address third-party software vulnerabilities per the Cisco Security Vulnerability Policy.
Multivendor Vulnerability Alert
Mozilla Firefox, Thunderbird, and SeaMonkey contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or execute arbitrary code with the privileges of the user.
Mozilla confirmed this vulnerability and released updated software.
Indicators of Compromise
The following Mozilla products are vulnerable:
Firefox versions prior to 3.0.14 and prior to 3.5.2
Thunderbird 188.8.131.52 and prior
SeaMonkey 1.1.18 and prior
Technical information is not available.
An attacker cannot exploit this vulnerability directly and instead relies on user interaction to accomplish an exploit. Attackers may send users links through e-mail, instant messaging, or other forms of communication and then use social engineering techniques that increase the likelihood that users will follow the link. An exploit could allow the attacker to terminate the Firefox browser or execute arbitrary code with the privileges of the user.
Systems that restrict user privileges may have a lowered exploit impact because any executed code would run with limited privileges. On systems that grant users elevated privileges, an attacker could execute code that may result in a complete system compromise.
Administrators are advised to apply the appropriate update.
Users are advised not to follow unsolicited links. Users should verify the authenticity of unexpected links prior to following them.
Users are advised not to open e-mail messages from untrusted sources.
Users are advised to run applications with the least necessary privileges.
Administrators are advised to monitor critical systems.
