aru Posted June 14, 2006 Report Share Posted June 14, 2006 Mandriva Advisories MDKSA-2006:099 : freetype2 Updated freetype2 packages fixes multiple vulnerabilities. June 12th, 2006 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. The released versions of Mandriva GNU/Linux affected are: CS3.0 MNF2.0 10.2 2006.0 Full information about this advisory, including the updated packages, is available at: www.mandriva.com/security/advisories?name=MDKSA-2006:099 Other references: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2661 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1861 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0747 Posted automatically by aru (mdksec2mub v: mdksec2mub,v 1.2 2006/06/01 20:04:28 pituko Exp $) Link to comment Share on other sites More sharing options...
