Multiple integer overflows in Xpdf 2.x and 3.x and Poppler 0.x, as used in the pdftops filter in CUPS 1.1.17, 1.1.22, and 1.3.7, GPdf, and kdegraphics KPDF, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PDF file that triggers a heap-based buffer overflow, possibly related to (1) Decrypt.cxx, (2) FoFiTrueType.cxx, (3) gmem.c, (4) JBIG2Stream.cxx, and (5) PSOutputDev.cxx in pdftops/. NOTE: the JBIG2Stream.cxx vector may overlap CVE-2009-1179.

PowerDNS Recursor before 3.1.6 does not always use the strongest random number generator for source port selection, which makes it easier for remote attack vectors to conduct DNS cache poisoning. NOTE: this is related to incomplete integration of security improvements associated with addressing CVE-2008-1637.

Integer overflow in Perl-Compatible Regular Expression (PCRE) library before 6.7 might allow context-dependent attackers to execute arbitrary code via a regular expression that involves large (1) min, (2) max, or (3) duplength values that cause an incorrect length calculation and trigger a buffer overflow, a different vulnerability than CVE-2006-7227. NOTE: this issue was originally subsumed by CVE-2006-7224, but that CVE has been REJECTED and split.
