pcre: stack overflow caused by mishandled group empty match (8.38/11)

PCRE 7.8 and 8.32 through 8.37, and PCRE2 10.10 mishandle group empty matches, which might allow remote attackers to cause a denial of service stack-based buffer overflow via a crafted regular expression, as demonstrated by /^?:?1\.|^\\W?++$/...

pcre: buffer overflow caused by patterns with duplicated named groups with (?| (8.38/27)

PCRE before 8.38 mishandles certain instances of the ?| substring, which allows remote attackers to cause a denial of service unintended recursion and buffer overflow or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object...

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...

pcre: buffer overflow caused by recursive back reference by name within certain group (8.38/4)

PCRE before 8.38 mishandles the /?J?'d'?'d'\gd/ pattern and related patterns with certain recursive back references, which allows remote attackers to cause a denial of service buffer overflow or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScri...

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...
