libicu in International Components for Unicode (ICU) 3.8.1 and earlier attempts to process backreferences to the nonexistent capture group zero (aka ), which might allow context-dependent attackers to read from, or write to, out-of-bounds memory locations, related to corruption of REStackFrames.

The regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows remote authenticated users to cause a denial of service (backend crash) via an out-of-bounds backref number.

Heap-based buffer overflow in Perl-Compatible Regular Expression (PCRE) library before 7.3 allows context-dependent attackers to execute arbitrary code via a singleton Unicode sequence in a character class in a regex pattern, which is incorrectly optimized.

Multiple integer overflows in Perl-Compatible Regular Expression (PCRE) library before 7.3 allow context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via unspecified escape (backslash) sequences.

Directory traversal vulnerability in pawfaliki.php in Pawfaliki 0.5.1 allows remote attackers to list arbitrary files via a .. (dot dot) in the page parameter. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
