CVE-2015-8386 4 Fedoraproject, Oracle, Pcre and 1 more 4 Fedora, Linux, Perl Compatible Regular Expression Library and 1 more 2025-04-12 7.5 HIGH 9.8 CRITICAL
PCRE before 8.38 mishandles the interaction of lookbehind assertions and mutually recursive subpatterns, 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 JavaScript RegExp object encountered by Konqueror.
CVE-2014-8964 6 Fedoraproject, Mariadb, Opensuse and 3 more 11 Fedora, Mariadb, Opensuse and 8 more 2025-04-12 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-2015-8389 3 Fedoraproject, Pcre, Php 3 Fedora, Perl Compatible Regular Expression Library, Php 2025-04-12 7.5 HIGH 9.8 CRITICAL
PCRE before 8.38 mishandles the /(?:|a|){100}x/ pattern and related patterns, which allows remote attackers to cause a denial of service (infinite recursion) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
CVE-2022-1586 5 Debian, Fedoraproject, Netapp and 2 more 18 Debian Linux, Fedora, Active Iq Unified Manager and 15 more 2025-03-25 6.4 MEDIUM 9.1 CRITICAL
An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT.
CVE-2022-41409 1 Pcre 1 Pcre2 2024-11-21 N/A 7.5 HIGH
Integer overflow vulnerability in pcre2test before 10.41 allows attackers to cause a denial of service or other unspecified impacts via negative input.
CVE-2022-1587 4 Fedoraproject, Netapp, Pcre and 1 more 17 Fedora, Active Iq Unified Manager, H300s and 14 more 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
An out-of-bounds read vulnerability was discovered in the PCRE2 library in the get_recurse_data_length() function of the pcre2_jit_compile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers.
CVE-2020-14155 6 Apple, Gitlab, Netapp and 3 more 20 Macos, Gitlab, Active Iq Unified Manager and 17 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
libpcre in PCRE before 8.44 allows an integer overflow via a large number after a (?C substring.
CVE-2019-20838 3 Apple, Pcre, Splunk 3 Macos, Pcre, Universal Forwarder 2024-11-21 4.3 MEDIUM 7.5 HIGH
libpcre in PCRE before 8.43 allows a subject buffer over-read in JIT when UTF is disabled, and \X or \R has more than one fixed quantifier, a related issue to CVE-2019-20454.
CVE-2019-20454 3 Fedoraproject, Pcre, Splunk 3 Fedora, Pcre2, Universal Forwarder 2024-11-21 5.0 MEDIUM 7.5 HIGH
An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is JIT compiled and used to match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may be vulnerable to this flaw, which would allow an attacker to crash the application. The flaw occurs in do_extuni_no_utf in pcre2_jit_compile.c.
CVE-2017-16231 1 Pcre 1 Pcre 2024-11-21 2.1 LOW 5.5 MEDIUM
In PCRE 8.41, after compiling, a pcretest load test PoC produces a crash overflow in the function match() in pcre_exec.c because of a self-recursive call. NOTE: third parties dispute the relevance of this report, noting that there are options that can be used to limit the amount of stack that is used
CVE-2015-2326 4 Mariadb, Opensuse, Pcre and 1 more 4 Mariadb, Opensuse, Pcre and 1 more 2024-11-21 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 2024-11-21 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.
