User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Mandrake 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.

 Mandriva Linux Security Advisory                         MDKSA-2006:099
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : freetype2
 Date    : June 12, 2006
 Affected: 10.2, 2006.0, Corporate 3.0, Multi Network Firewall 2.0

 Problem 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.  
 
 Packages have been patched to correct this issue.
