PCRE before 8.36 mishandles the /((?(R)a|(?1)))+/ pattern and related patterns with certain recursion, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

The pcre_compile function in pcre_compile.c in PCRE before 8.38 mishandles certain [: nesting, which allows remote attackers to cause a denial of service (CPU consumption) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

Heap-based buffer overflow in the find_fixedlength function in pcre_compile.c in PCRE before 8.38 allows remote attackers to cause a denial of service (crash) or obtain sensitive information from heap memory and possibly bypass the ASLR protection mechanism via a crafted regular expression with an excess closing parenthesis.

https://notcve.org/view.php?id=CVE-2015-2326
The pcre_compile2 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 "((?+1)(\1))/". La función pcre_compile2 en PCRE versiones anteriores a 8.37, permite a atacantes dependiendo del contexto compilar código incorrecto y causar una denegación de servicio (lectura fuera de límites) mediante una expresión regular con un grupo que contiene una llamada de subrutina de referencia directa y una referencia inversa recursiva, como es demostrado por "((? +1)(\1))/". • http://lists.opensuse.org/opensuse-updates/2015-05/msg00014.html https://bugs.exim.org/show_bug.cgi?id=1592 https://fortiguard.com/zeroday/FG-VD-15-016 https://www.pcre.org/original/changelog.txt https://access.redhat.com/security/cve/CVE-2015-2326 https://bugzilla.redhat.com/show_bug.cgi?id=1207202 • CWE-125: Out-of-bounds Read •

The compile_branch function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code, cause a denial of service (out-of-bounds heap read and crash), or possibly have other unspecified impact via a regular expression with a group containing a forward reference repeated a large number of times within a repeated outer group that has a zero minimum quantifier.
