Synopsis :

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

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.

# 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'
