Synopsis

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

Description

Alexander Cherepanov reports :

7z (and 7zr) is susceptible to a directory traversal vulnerability.
While extracting an archive, it will extract symlinks and then follow them if they are referenced in further entries. This can be exploited by a rogue archive to write files outside the current directory.

Solution

Update the affected package.
