Gentoo Linux Security Advisory
Title: libTIFF: Buffer overflow (GLSA 200505-07)
Severity: normal
Exploitable: remote
Date: May 10, 2005
Updated: May 22, 2006
Bug(s): #91584
ID: 200505-07
Synopsis
The libTIFF library is vulnerable to a buffer overflow, potentially resulting in the execution of arbitrary code.
Background
libTIFF provides support for reading and manipulating TIFF (Tag Image File Format) images.
Affected Packages
Package: media-libs/tiff
Vulnerable: < 3.7.2
Unaffected: >= 3.7.2
Architectures: All supported architectures
Description
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a stack based buffer overflow in the libTIFF library when reading a TIFF image with a malformed BitsPerSample tag.
Impact
Successful exploitation would require the victim to open a specially crafted TIFF image, resulting in the execution of arbitrary code.
Workaround
There is no known workaround at this time.
Resolution
All libTIFF users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.7.2" |
