Debian DSA-3034-1 : iceweasel - security update
High Nessus Plugin ID 77881
SynopsisThe remote Debian host is missing a security-related update.
DescriptionAntoine Delignat-Lavaud from Inria discovered an issue in the way NSS (the Mozilla Network Security Service library, embedded in Wheezy's Iceweasel package), was parsing ASN.1 data used in signatures, making it vulnerable to a signature forgery attack.
An attacker could craft ASN.1 data to forge RSA certificates with a valid certification chain to a trusted CA.
SolutionUpgrade the iceweasel packages.
For the stable distribution (wheezy), this problem has been fixed in version 24.8.1esr-1~deb7u1.
