Mandrake Linux Security Advisory : unzip (MDKSA-2003:073-1)

This script is Copyright (C) 2004-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandrake Linux host is missing a security update.

Description :

A vulnerability was discovered in unzip 5.50 and earlier that allows
attackers to overwrite arbitrary files during archive extraction by
placing non-printable characters between two '.' characters. These
invalid characters are filtered which results in a '..' sequence.

The patch applied to these packages prevents unzip from writing to
parent directories unless the '-:' command line option is used.

Update :

Ben Laurie found that the original patch used to fix this issue missed
a case where the path component included a quoted slash. An updated
patch was used to build these packages.

Low / CVSS Base Score : 2.6
