Multiple vulnerabilities have been discovered in XV, potentially resulting in the execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/xv | * | < 3.10a-r11 | >= 3.10a-r11 |
XV is an interactive image manipulation program for the X Window System.
Greg Roelofs has reported multiple input validation errors in XV image decoders. Tavis Ormandy of the Gentoo Linux Security Audit Team has reported insufficient validation in the PDS (Planetary Data System) image decoder, format string vulnerabilities in the TIFF and PDS decoders, and insufficient protection from shell meta-characters in malformed filenames.
Successful exploitation would require a victim to view a specially created image file using XV, potentially resulting in the execution of arbitrary code.
There is no known workaround at this time.
All XV users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r11"
xv contains a format string vulnerability, potentially resulting in the execution of arbitrary code.

xv is an interactive image manipulation package for X11.
Tavis Ormandy of the Gentoo Linux Security Audit Team identified a flaw in the handling of image filenames by xv.
Successful exploitation would require a victim to process a specially crafted image with a malformed filename, potentially resulting in the execution of arbitrary code.
There is no known workaround at this time.
All xv users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/xv-3.10a-r10"
Multiple heap-based overflows have been found in the tiff library image decoding routines, potentially allowing to execute arbitrary code with the rights of the user viewing a malicious image.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/xv | * | <= 3.10a-r7 | >= 3.10a-r8 |
| media-libs/tiff | * | < 3.6.1-r2 | >= 3.6.1-r2 |
The tiff library contains encoding and decoding routines for the Tag Image File Format. It is called by numerous programs, including GNOME and KDE, to help in displaying TIFF images. xv is a multi-format image manipulation utility that is statically linked to the tiff library.
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.
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"
xv contains multiple exploitable buffer overflows in the image handling code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/xv | * | < 3.10a-r7 | >= 3.10a-r7 |
xv is a multi-format image manipulation utility.
Multiple buffer overflow and integer handling vulnerabilities have been discovered in xv's image processing code. These vulnerabilities have been found in the xvbmp.c, xviris.c, xvpcx.c and xvpm.c source files.
An attacker might be able to embed malicious code into an image, which would lead to the execution of arbitrary code under the privileges of the user viewing the image.
There is no known workaround at this time.
All xv users should upgrade to the latest stable version:
# emerge sync # emerge -pv ">=media-gfx/xv-3.10a-r7" # emerge ">=media-gfx/xv-3.10a-r7"
