Mandriva Linux Security Advisory 2009-041 – Security vulnerabilities have been identified and fixed in jhead. Buffer overflow in the DoCommand function in jhead before 2.84 might allow context-dependent attackers to cause a denial of service (crash). Jhead before 2.84 allows local users to overwrite arbitrary files via a symlink attack on a temporary file. Jhead 2.84 and earlier allows local users to delete arbitrary files via vectors involving a modified input filename. jhead 2.84 and earlier allows attackers to execute arbitrary commands via shell metacharacters in unspecified input. This update provides the latest Jhead to correct these issues.
