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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/tiff < 3.7.2 >= 3.7.2
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:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.7.2"
References ==========
