Multiple vulnerabilities have been found in libpcre, the worst of
    which could lead to arbitrary code execution, or cause a Denial of Service
    condition.

Improper Restriction of Operations within the Bounds of a Memory Buffer
PCRE2 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."

Improper Restriction of Operations within the Bounds of a Memory Buffer
pcre2test.c in PCRE2 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression.

Out-of-bounds Read
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.

Out-of-bounds Read
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.

Integer Overflow or Wraparound
Integer overflow vulnerability in pcre2test before 10.41 allows attackers to cause a denial of service or other unspecified impacts via negative input.

A vulnerability in PCRE2 could lead to a Denial of Service
    condition.

Improper Restriction of Operations within the Bounds of a Memory Buffer
The compile_branch function in pcre_compile.c in PCRE and pcre2_compile.c in PCRE2 mishandles patterns containing an (*ACCEPT) substring in conjunction with nested parentheses, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror, aka ZDI-CAN-3542.

Multiple vulnerabilities have been found in libpcre, the worst of
    which could lead to arbitrary code execution, or cause a Denial of Service
    condition.

Improper Restriction of Operations within the Bounds of a Memory Buffer
libpcre1 in PCRE and libpcre2 in PCRE2 allow remote attackers to cause a denial of service (segmentation violation for read access, and application crash) by triggering an invalid Unicode property lookup.
