libTIFF: Buffer overflow

libTIFF: Buffer overflow The libTIFF library is vulnerable to a buffer overflow, potentially resulting in the execution of arbitrary code. tiff 2005-05-10 2006-05-22 91584 remote 3.7.2 3.7.2

libTIFF provides support for reading and manipulating TIFF (Tag Image File Format) images.

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"
