63d61427844f29c8b6e7dc2bb27976f5d4dd7c9f8fd7a49ed4c6645fc811806cMandriva Linux Security Advisory 2010-210 - Mozilla Firefox before 3.5.14 and 3.6.x before 3.6.11, Thunderbird before 3.0.9 and 3.1.x before 3.1.5, and SeaMonkey before 2.0.9 recognize a wildcard IP address in the subject's Common Name field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority. The SSL implementation in Mozilla Firefox before 3.5.14 and 3.6.x before 3.6.11, Thunderbird before 3.0.9 and 3.1.x before 3.1.5, and SeaMonkey before 2.0.9 does not properly set the minimum key length for Diffie-Hellman Ephemeral mode, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. Various other issues have also been addressed.

An attacker could exploit this to crash the browser or possibly run arbitrary code as the user invoking the program. Alexander Miller, Sergey Glazunov, and others discovered several flaws in the JavaScript engine. An attacker could exploit this to crash the browser or possibly run arbitrary code as the user invoking the program. Robert Swiecki discovered that Firefox did not properly validate Gopher URLs. If a user were tricked into opening a crafted file via Gopher, an attacker could possibly run arbitrary JavaScript. Eduardo Vela Nava discovered that Firefox could be made to violate the same-origin policy by using modal calls with JavaScript. An attacker could exploit this to steal information from another site. Dmitri GribenkoDmitri Gribenko discovered that Firefox did not properly setup the LD_LIBRARY_PATH environment variable. A local attacker could exploit this to execute arbitrary code as the user invoking the program.
