xv contains multiple exploitable buffer overflows in the image handling code.

2.  Impact Information


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.

3.  Resolution Information


There is no known workaround at this time.


All xv users should upgrade to the latest stable version:

Code Listing 3.1: Resolution

# emerge sync
# emerge -pv ">=media-gfx/xv-3.10a-r7"
# emerge ">=media-gfx/xv-3.10a-r7"
