|2020-06-15||CVE-2020-14155|| Integer Overflow OR Wraparound vulnerability in multiple products |
libpcre in PCRE before 8.44 allows an integer overflow via a large number after a (?C substring.
| 5.0 |
|2020-06-15||CVE-2019-20838|| Out-Of-Bounds Read vulnerability in multiple products |
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.
| 4.3 |
|2020-02-14||CVE-2019-20454|| Out-Of-Bounds Read vulnerability in Pcre Pcre2 10.31/10.32/10.33 |
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.
| 5.0 |
|2020-01-14||CVE-2015-2326|| Out-Of-Bounds Read vulnerability in multiple products |
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))/".
| 4.3 |
|2020-01-14||CVE-2015-2325|| Out-Of-Bounds Read vulnerability in multiple products |
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.

|2019-03-21||CVE-2017-16231|| Buffer Errors vulnerability in Pcre 8.41 |
** DISPUTED ** 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.
| 2.1 |
|2017-07-11||CVE-2017-11164|| Uncontrolled Recursion vulnerability in Pcre 8.41 |
In PCRE 8.41, the OP_KETRMAX feature in the match function in pcre_exec.c allows stack exhaustion (uncontrolled recursion) when processing a crafted regular expression.
| 7.8 |
|2017-05-05||CVE-2017-8786|| Buffer Errors vulnerability in Pcre Pcre2 10.23 |
pcre2test.c in PCRE2 10.23 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression.
| 7.5 |
|2017-05-01||CVE-2017-8399|| Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in Pcre Pcre2 |
PCRE2 before 10.30 has an out-of-bounds write caused by a stack-based buffer overflow in pcre2_match.c, related to a "pattern with very many captures."
| 7.5 |
|2017-03-23||CVE-2017-7246|| Buffer Errors vulnerability in Pcre 8.40 |
Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (WRITE of size 268) or possibly have unspecified other impact via a crafted file.
