cairo: Stack-based buffer overflow via parsing of crafted WebKitGTK+ document

Published Oct 8, 2018

Description

cairo through 1.15.14 has an out-of-bounds stack-memory write during processing of a crafted document by WebKitGTK+ because of the interaction between cairo-rectangular-scan-converter.c (the generate and render_rows functions) and cairo-image-compositor.c (the _cairo_image_spans_and_zero function).

Affected products

Remediation

Red Hat mitigation

Attackers can use specially-crafted files to trigger this stack-buffer overflow in cairo. Applications compiled with cairo, which do not parse untrusted 2D image files are not vulnerable to this flaw. cairo package in Red Hat Enterprise Linux 7 and 8 is compiled with gcc's Stack Smashing Protection, which may reduce the impact of this flaw to crash only.
