What is CVE-2008-5012?
CVE-2008-5012 is a medium-severity vulnerability in Mozilla Firefox, published on 13 Nov 2008. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
