Package Instance

This GLSA contains notification of vulnerabilities found in several
    Gentoo packages which have been fixed prior to January 1, 2012. The worst
    of these vulnerabilities could lead to local privilege escalation and
    remote code execution. Please see the package list and CVE identifiers
    below for more information.

Multiple vulnerabilities have been found in GraphicsMagick,
    allowing remote attackers to execute arbitrary code or cause a Denial of
    Service condition.

XML signature HMAC truncation authentication bypass
This package uses a parameter that defines an HMAC truncation length (`HMACOutputLength`) but does not require a minimum for this length, which allows attackers to spoof HMAC-based signatures and bypass authentication by specifying a truncation length with a small number of bits.
