|Gentoo Linux Security Advisory
Title: libTIFF: Buffer overflow (GLSA 200505-07)
Date: May 10, 2005
Updated: May 22, 2006
The libTIFF library is vulnerable to a buffer overflow, potentially resulting in the execution of arbitrary code.
libTIFF provides support for reading and manipulating TIFF (Tag Image File Format) images.
Vulnerable: < 3.7.2
Unaffected: >= 3.7.2
Architectures: All supported architectures
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.
Successful exploitation would require the victim to open a specially crafted TIFF image, resulting in the execution of arbitrary code.
There is no known workaround at this time.
All libTIFF users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.7.2"
