Vulnerability Assessment Details

[GLSA-200410-11] tiff: Buffer overflows in image decoding

Vulnerability Assessment Summary
tiff: Buffer overflows in image decoding

Detailed Explanation for this Vulnerability Assessment
The 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.

Impact

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.

Workaround

There is no known workaround at this time.

Solution:
All 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"
