GLSA-200604-10 : zgv, xzgv: Heap overflow

high Nessus Plugin ID 21256

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200604-10 (zgv, xzgv: Heap overflow)

 Andrea Barisani of Gentoo Linux discovered xzgv and zgv allocate insufficient memory when rendering images with more than 3 output components, such as images using the YCCK or CMYK colour space. When xzgv or zgv attempt to render the image, data from the image overruns a heap allocated buffer.
 Impact :

 An attacker may be able to construct a malicious image that executes arbitrary code with the permissions of the xzgv or zgv user when attempting to render the image.
 Workaround :

 There is no known workaround at this time.

Solution

All xzgv users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/xzgv-0.8-r2' All zgv users should also upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/zgv-5.9'
