CVE-2007-5116

Buffer overflow in the polymorphic opcode support in the Regular Expression Engine regcomp.c in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode UTF characters in a regular expression...

CVE-2007-4768

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...

DEBIAN-CVE-2007-1662

Perl-Compatible Regular Expression PCRE library before 7.3 reads past the end of the string when searching for unmatched brackets and parentheses, which allows context-dependent attackers to cause a denial of service crash, possibly involving forward references...

DenyHosts: Denial of service

Background DenyHosts is designed to monitor SSH servers for repeated failed login attempts. Description Daniel B. Cid discovered that DenyHosts used an incomplete regular expression to parse failed login attempts, a different issue than GLSA 200701-01. Impact A remote unauthenticated attacker can...
