GLSA-200410-11 : tiff: Buffer overflows in image decoding
High Nessus Plugin ID 15472
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200410-11 (tiff: Buffer overflows in image decoding)
Chris Evans found heap-based overflows in RLE decoding routines in tif_next.c, tif_thunder.c and potentially tif_luv.c.
A remote attacker could entice a user to view a carefully crafted TIFF image file, which would potentially lead to execution of arbitrary code with the rights of the user viewing the image. This affects any program that makes use of the tiff library, including GNOME and KDE web browsers or mail readers.
There is no known workaround at this time.
SolutionAll tiff library users should upgrade to the latest version:
# emerge sync # emerge -pv '>=media-libs/tiff-3.6.1-r2' # emerge '>=media-libs/tiff-3.6.1-r2' xv makes use of the tiff library and needs to be recompiled to receive the new patched version of the library. All xv users should also upgrade to the latest version:
# emerge sync # emerge -pv '>=media-gfx/xv-3.10a-r8' # emerge '>=media-gfx/xv-3.10a-r8'
