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

High Nessus Plugin ID 21256


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


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.


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'
