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.

PCRE before 8.38 mishandles the (?(<digits>) and (?(R<digits>) conditions, which allows remote attackers to cause a denial of service (integer overflow) 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. Desbordamiento de búfer basado en memoria dinámica en la función find_fixedlength en pcre_compile.c en PCRE en versiones anteriores a 8.38 permite a atacantes remotos provocar una denegación de servicio (caída) u obtener información sensible de la memoria dinámica y posiblemente eludir el mecanismo de protección ASLR a través de una expresión regular manipulada con un paréntesis de cierre excesivo. • http://rhn.redhat.com/errata/RHSA-2016-1025.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://vcs.pcre.org/pcre/code/trunk/ChangeLog?revision=1609&view=markup http://vcs.pcre.org/pcre?view=revision&revision=1571 http://www-01.ibm.com/support/docview.wss?uid=isg3T1023886 http://www.openwall.com/lists/oss-security/2015/06/26/1 http://www.openwall.com/lists/oss-security/2015/06/26/3 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Heap-based buffer overflow in PCRE 8.34 through 8.37 and PCRE2 10.10 allows remote attackers to execute arbitrary code via a crafted regular expression, as demonstrated by /^(?P=B)((?P=B)(?J:(?P<B>c)(? • http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.openwall.com/lists/oss-security/2015/06/01/7 http://www.openwall.com/lists/oss-security/2015/12/02/11 http://www.securityfocus.com/bid/74934 https://access.redhat.com/errata/RHSA-2016:1132 https://bugs.exim.org/show_bug.cgi?id=1636 https://access.redhat.com/security/cve/CVE-2015-3210 https://bugzilla.redhat.com/show_bug.cgi?id=1287623 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 •
