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.
CVE-2015-2327 1 Pcre 1 Perl Compatible Regular Expression Library 2026-06-17 7.5 HIGH N/A
PCRE before 8.36 mishandles the /(((a\2)|(a*)\g<-1>))*/ pattern and related patterns with certain internal recursive back references, 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.
CVE-2015-2326 4 Mariadb, Opensuse, Pcre and 1 more 4 Mariadb, Opensuse, Pcre and 1 more 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
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))/".
CVE-2015-2325 4 Mariadb, Opensuse, Pcre and 1 more 4 Mariadb, Opensuse, Pcre and 1 more 2026-06-17 6.8 MEDIUM 7.8 HIGH
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.
CVE-2014-9769 1 Pcre 1 Pcre 2026-06-17 7.5 HIGH 7.3 HIGH
pcre_jit_compile.c in PCRE 8.35 does not properly use table jumps to optimize nested alternatives, which allows remote attackers to cause a denial of service (stack memory corruption) or possibly have unspecified other impact via a crafted string, as demonstrated by packets encountered by Suricata during use of a regular expression in an Emerging Threats Open ruleset.
CVE-2014-8964 6 Fedoraproject, Mariadb, Opensuse and 3 more 11 Fedora, Mariadb, Opensuse and 8 more 2026-06-17 5.0 MEDIUM N/A
Heap-based buffer overflow in PCRE 8.36 and earlier allows remote attackers to cause a denial of service (crash) or have other unspecified impact via a crafted regular expression, related to an assertion that allows zero repeats.
CVE-2011-1951 2 Oneidentity, Pcre 2 Syslog-ng, Pcre 2026-06-16 4.3 MEDIUM N/A
lib/logmatcher.c in Balabit syslog-ng before 3.2.4, when the global flag is set and when using PCRE 8.12 and possibly other versions, allows remote attackers to cause a denial of service (memory consumption) via a message that does not match a regular expression.
CVE-2008-2371 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-16 7.5 HIGH N/A
Heap-based buffer overflow in pcre_compile.c in the Perl-Compatible Regular Expression (PCRE) library 7.7 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a regular expression that begins with an option and contains multiple branches.
CVE-2008-0674 1 Pcre 1 Pcre 2026-06-16 7.5 HIGH N/A
Buffer overflow in PCRE before 7.6 allows remote attackers to execute arbitrary code via a regular expression containing a character class with a large number of characters with Unicode code points greater than 255.
CVE-2007-4768 1 Pcre 1 Pcre 2026-06-16 6.8 MEDIUM N/A
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.
CVE-2007-4767 1 Pcre 1 Pcre 2026-06-16 5.0 MEDIUM N/A
Perl-Compatible Regular Expression (PCRE) library before 7.3 does not properly compute the length of (1) a \p sequence, (2) a \P sequence, or (3) a \P{x} sequence, which allows context-dependent attackers to cause a denial of service (infinite loop or crash) or execute arbitrary code.
CVE-2007-4766 1 Pcre 1 Pcre 2026-06-16 7.5 HIGH N/A
Multiple integer overflows in Perl-Compatible Regular Expression (PCRE) library before 7.3 allow context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via unspecified escape (backslash) sequences.
CVE-2007-1662 1 Pcre 1 Pcre 2026-06-16 5.0 MEDIUM N/A
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.
CVE-2007-1661 2 Apple, Pcre 3 Mac Os X, Mac Os X Server, Perl-compatible Regular Expression Library 2026-06-16 6.4 MEDIUM N/A
Perl-Compatible Regular Expression (PCRE) library before 7.3 backtracks too far when matching certain input bytes against some regex patterns in non-UTF-8 mode, which allows context-dependent attackers to obtain sensitive information or cause a denial of service (crash), as demonstrated by the "\X?\d" and "\P{L}?\d" patterns.
CVE-2007-1660 1 Pcre 1 Pcre 2026-06-16 6.8 MEDIUM N/A
Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate sizes for unspecified "multiple forms of character class", which triggers a buffer overflow that allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code.

CVE-2006-7230 1 Pcre 1 Pcre 2026-06-16 4.3 MEDIUM N/A
Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate the amount of memory needed for a compiled regular expression pattern when the (1) -x or (2) -i UTF-8 options change within the pattern, which allows context-dependent attackers to cause a denial of service (PCRE or glibc crash) via crafted regular expressions.
