FreeBSD : gtar -- invalid headers buffer overflow (6107efb9-aae3-11da-aea1-000854d03344)

medium Nessus Plugin ID 21437


The remote FreeBSD host is missing a security-related update.


GNU tar is vulnerable to a buffer overflow, caused by improper bounds checking of the PAX extended headers. By tricking an user into processing a specially crafted tar archive, this could be exploited to execute arbitrary code with the privileges of the user.


Update the affected package.
