Vulnerability details

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the xattr_decoder() function in xheader.c.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
