Synopsis


A vulnerability has been discovered in FreeType allowing for user-assisted remote execution of arbitrary code.

Background


FreeType is a True Type Font rendering library.

Affected packages



Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/freetype < 2.1.10-r3 >= 2.1.10-r3

Description


Greg MacManus of iDefense Labs has discovered an integer overflow in the function bdfReadCharacters() when parsing BDF fonts.

Impact


A remote attacker could entice a user to use a specially crafted BDF font, possibly resulting in a heap-based buffer overflow and the remote execution of arbitrary code.

Workaround


There is no known workaround at this time.

Resolution


All FreeType users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/freetype-2.1.10-r3"
