CVE-2008-5012: n/a vulnerability

CVE-2008-5012: Mozilla Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 do no...

Mozilla Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 do not properly change the source URI when processing a canvas element and an HTTP redirect, which allows remote attackers to bypass the same origin policy and access arbitrary images that are not directly accessible to the attacker. NOTE: this issue can be leveraged to enumerate software on the client by performing redirections related to moz-icon.

Security readout for executives and security teams

This flaw affected old Mozilla clients. A malicious site could abuse canvas handling with HTTP redirects to bypass browser same-origin protections and read images the attacker should not access. The CVE also notes possible client software enumeration through moz-icon redirects. Exposure is most likely limited to legacy systems still running the affected Mozilla versions or distribution backports without the relevant security updates. Modern supported browsers are not identified as affected in the supplied sources. Treat this as a legacy exposure cleanup item unless affected versions are still present. Prioritize remediation where outdated browsers or mail clients handle untrusted web or email content. Mitigation focus: Upgrade Firefox to 2.0.0.18 or later where still applicable.; Upgrade Thunderbird to 2.0.0.18 or later where still applicable.; Upgrade SeaMonkey to 1.1.13 or later where still applicable..
