Vulnerability from variot
xar in Apple Mac OS X 10.5.8 does not properly validate package signatures, which allows attackers to have an unspecified impact via a modified package. xar (eXtensible ARchiver) is prone to a security-bypass vulnerability because it fails to properly verify signatures in a modified xar archive. Attackers can exploit this issue to make modified archives appear to have a valid signature. This may lead to other attacks. Versions prior to xar 1.5.3 are vulnerable. NOTE: This issue was previously covered in BID 39020 (Apple Mac OS X APPLE-SA-2010-03-29-1 Multiple Security Vulnerabilities) but has been assigned its own record to better document it. Mac OS X is the operating system used by the Apple family of machines. A remote attacker forges a modified package as a validly signed package, causing unknown impact
