GLSA-200905-05 : FreeType: Multiple vulnerabilities
Critical Nessus Plugin ID 38886
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200905-05 (FreeType: Multiple vulnerabilities)
Tavis Ormandy reported multiple integer overflows in the cff_charset_compute_cids() function in cff/cffload.c, sfnt/tccmap.c and the ft_smooth_render_generic() function in smooth/ftsmooth.c, possibly leading to heap or stack-based buffer overflows.
A remote attacker could entice a user or automated system to open a specially crafted font file, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
SolutionAll FreeType users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/freetype-2.3.9-r1'
