Severity: Normal Title: zgv, xzgv: Heap overflow Date: April 21, 2006 Bugs: #127008 ID: 200604-10

Synopsis ========
xzgv and zgv attempt to decode JPEG images within the CMYK/YCCK colour space incorrectly, potentially resulting in the execution of arbitrary code.
Background ==========
xzgv and zgv are picture viewing utilities with a thumbnail based file selector.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/xzgv < 0.8-r2 >= 0.8-r2 2 media-gfx/zgv < 5.8 >= 5.8 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
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.
Resolution ==========
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-5.8"
