Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple integer overflows in FreeType might allow for the remote
execution of arbitrary code or a Denial of Service.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
FreeType is a high-quality and portable font engine.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/freetype < 2.3.9-r1 >=3D 2.3.9-r1
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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.
Impact
=3D=3D=3D=3D=3D=3D
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.
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 FreeType users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-libs/freetype-2.3.9-r1"
