Synopsis

A vulnerability in VIPS could result in privilege escalation.

2.  Impact Information

Background

VIPS is a free image processing system.

Description

VIPS places a zero-length directory name in the LD_LIBRARY_PATH, which might result in the current working directory (.) to be included when searching for dynamically linked libraries.

Impact

A local attacker could gain escalated privileges via a specially crafted shared library.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All VIPS users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/vips-7.22.4"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since November 23, 2010. It is likely that your system is already no longer affected by this issue.
