Related bugreports: #172577


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

2.  Impact Information


FreeType is a True Type Font rendering library.


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


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.

3.  Resolution Information


There is no known workaround at this time.


All FreeType users should upgrade to the latest version:

Code Listing 3.1: Resolution

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