Gentoo Linux Security Advisory

Title: Star: Directory traversal vulnerability (GLSA 200710-23)
Severity: low
Exploitable: remote
Date: October 22, 2007
Bug(s): #189690
ID: 200710-23

Synopsis

A directory traversal vulnerability has been discovered in Star.

Background

The Star program provides the ability to create and extract tar archives.

Affected Packages

Package: app-arch/star
Vulnerable: < 1.5_alpha84
Unaffected: >= 1.5_alpha84
Architectures: All supported architectures


Description

Robert Buchholz of the Gentoo Security team discovered a directory traversal vulnerability in the has_dotdot() function which does not identify //.. (slash slash dot dot) sequences in file names inside tar files.

Impact

By enticing a user to extract a specially crafted tar archive, a remote attacker could extract files to arbitrary locations outside of the specified directory with the permissions of the user running Star.

Workaround

There is no known workaround at this time.

Resolution

All Star users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/star-1.5_alpha84"
