pcre: heap buffer over-read in pcre_compile2() (8.37/23)

The pcrecompile2 function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code and cause a denial of service out-of-bounds read via regular expression with a group containing both a forward referencing subroutine call and a recursive back reference, as demonstrated by...

pcre: workspace overflow for (*ACCEPT) with deeply nested parentheses (8.39/13, 10.22/12)

The compilebranch function in pcrecompile.c in PCRE 8.x before 8.39 and pcre2compile.c in PCRE2 before 10.22 mishandles patterns containing an ACCEPT substring in conjunction with nested parentheses, which allows remote attackers to execute arbitrary code or cause a denial of service stack-based...

pcre: heap buffer overflow in handling of duplicate named groups (8.39/14)

The pcrecompile2 function in pcrecompile.c in PCRE 8.38 mishandles the /?:F?+?:^?Ra+"99-?J?'R'?'R'?'RR'?'R'\97?J?J?'R'?'R'\99|:?|?'R'\k'R'|?'R'H'R'RH'R/ pattern and related patterns with named subgroups, which allows remote attackers to cause a denial of service heap-based buffer overflow or...

MGASA-2016-0191 Updated perl packages fix security vulnerability

The regex engine got into an infinite loop because of the malformation. It is trying to back-up over a sequence of UTF-8 continuation bytes. The character just before the sequence should be a start byte. If it's not, there is a malformation which results in "hang" of regexp matching and CPU...
