Mandriva Linux Security Advisory 2010-094

Mandriva Linux Security Advisory 2010-094 - Buffer overflow in BibTeX 0.99 allows context-dependent attackers to cause a denial of service (memory corruption and crash) via a long.bib bibliography file. Integer overflow in the ObjectStream::ObjectStream function in XRef.cc in Xpdf 3.x before 3.02pl4 and Poppler before 0.12.1, as used in GPdf, kdegraphics KPDF, CUPS pdftops, and teTeX, might allow remote attackers to execute arbitrary code via a crafted PDF document that triggers a heap-based buffer overflow. Integer overflow in dvips in TeX Live 2009 and earlier, and teTeX, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted virtual font (VF) file associated with a DVI file. Multiple array index errors in set.c in dvipng 1.11 and 1.12, and teTeX, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed DVI file. Integer overflow in the predospecial function in dospecial.c in dvips in (1) TeX Live and (2) teTeX might allow user-assisted remote attackers to execute arbitrary code via a crafted DVI file that triggers a heap-based buffer overflow. Multiple integer overflows in dvipsk/dospecial.c in dvips in TeX Live 2009 and earlier, and teTeX, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a special command in a DVI file, related to the (1) predospecial and (2) bbdospecial functions, a different vulnerability than CVE-2010-0739. Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products. The corrected packages solves these problems.
