Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

zgv contains multiple buffer overflows that can potentially lead to the
execution of arbitrary code.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

zgv is a console image viewer based on svgalib.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3 D

-------------------------------------------------------------------
Package / Vulnerable / Unaffected

1 media-gfx/zgv < 5.8 >=3D 5.8

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Multiple arithmetic overflows have been detected in the image
processing code of zgv.

Impact
=3D=3D=3D=3D=3D=3D

An attacker could entice a user to open a specially-crafted image file,
potentially resulting in execution of arbitrary code with the rights of
the user running zgv.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All zgv users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-gfx/zgv-5.8"
