Vulnerability Assessment Details

MDKSA-2006:099-1: freetype2

Vulnerability Assessment Summary
Check for the version of the freetype2 package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2006:099-1 (freetype2).

Integer underflow in Freetype before 2.2 permits remote attackers to cause

a denial of service (crash) via a font file with an odd number of blue

values, which causes the underflow when decrementing by 2 in a context

that assumes an even number of values. (CVE-2006-0747)

Multiple integer overflows in FreeType before 2.2 permit remote attackers to

cause a denial of service (crash) and possibly execute arbitrary code via

attack vectors related to (1) bdf/bdflib.c, (2) sfnt/ttcmap.c,

(3) cff/cffgload.c, and (4) the read_lwfn function and a crafted LWFN file

in base/ftmac.c. (CVE-2006-1861)

Ftutil.c in Freetype before 2.2 permits remote attackers to cause a denial

of service (crash) via a crafted font file that triggers a null dereference.

(CVE-2006-2661)

In addition, a patch is applied to 2.1.10 in Mandriva 2006 to fix a serious

bug in ttkern.c that caused some programs to go into an infinite loop when

dealing with fonts that don't have a properly sorted kerning sub-table.

This patch is not applicable to the earlier Mandriva releases.

Update:

The previous update introduced some issues with other applications and

libraries linked to libfreetype, that were missed in testing for the

vulnerabilty issues. The new packages correct these issues.
