Mandrake Linux Security Advisory : freetype2 (MDKSA-2006:099-1)

This script is Copyright (C) 2006-2017 Tenable Network Security, Inc.

Synopsis :

The remote Mandrake Linux host is missing one or more security

Description :

Integer underflow in Freetype before 2.2 allows 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 allow 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 allows 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
vulnerability issues. The new packages correct these issues.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.5
CVSS Temporal Score : 7.5
Public Exploit Available : false
