libTIFF contains several vulnerabilities that could result in arbitrary code execution.
Package | media-libs/tiff on all architectures |
---|---|
Affected versions | < 3.8.2-r2 |
Unaffected versions | >= 3.8.2-r2 |
libTIFF provides support for reading and manipulating TIFF images.
Tavis Ormandy of the Google Security Team discovered several heap and stack buffer overflows and other flaws in libTIFF. The affected parts include the TIFFFetchShortPair(), TIFFScanLineSize() and EstimateStripByteCounts() functions, and the PixarLog and NeXT RLE decoders.
A remote attacker could entice a user to open a specially crafted TIFF file, resulting in the possible 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-3.8.2-r2"
