Debian Pcre2 vulnerabilities

CVE-2016-3191 [CRITICAL] CVE-2016-3191: pcre2 - The compile_branch function in pcre_compile.c in PCRE 8.x before 8.39 and pcre2_... The compile_branch function in pcre_compile.c in PCRE 8.x before 8.39 and pcre2_compile.c in PCRE2 before 10.22 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 demonstrat

CVE-2025-58050 [MEDIUM] CVE-2025-58050: pcre2 - The PCRE2 library is a set of C functions that implement regular expression patt... The PCRE2 library is a set of C functions that implement regular expression pattern matching. In version 10.45, a heap-buffer-overflow read vulnerability exists in the PCRE2 regular expression matching engine, specifically within the handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. This vulnerability may potentially

CVE-2016-1283 [CRITICAL] CVE-2016-1283: pcre2 - The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles the /((?:F?... The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles the /((?:F?+(?:^(?(R)a+\"){99}-))(?J)(?'R'(?'R'<((?'RR'(?'R'\){97)?J)?J)(?'R'(?'R'\){99|(:(?|(?'R')(\k'R')|((?'R')))H'R'R)(H'R))))))/ pattern and related patterns with named subgroups, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecifi

CVE-2022-1587 [CRITICAL] CVE-2022-1587: pcre2 - An out-of-bounds read vulnerability was discovered in the PCRE2 library in the g... 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. Scope: local bookworm: resolved (fixed in 10.40-1) bullseye: resolved (fixed in 10.36-2+deb11u1) forky: resolved (fixed

CVE-2017-8786 [CRITICAL] CVE-2017-8786: pcre2 - pcre2test.c in PCRE2 10.23 allows remote attackers to cause a denial of service ... 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.

CVE-2022-1586 [CRITICAL] CVE-2022-1586: pcre2 - An out-of-bounds read vulnerability was discovered in the PCRE2 library in the c... 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. Scope: local bookworm: resolved (fixed i

CVE-2015-8380 [HIGH] CVE-2015-8380: pcre2 - The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a // patter... The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a // pattern with a \01 string, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. Scope: local bookworm: resolved bul

CVE-2019-20454 [HIGH] CVE-2019-20454: pcre2 - An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is... 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. Scope: local b

CVE-2017-7186 [HIGH] CVE-2017-7186: pcre2 - libpcre1 in PCRE 8.40 and libpcre2 in PCRE2 10.23 allow remote attackers to caus... libpcre1 in PCRE 8.40 and libpcre2 in PCRE2 10.23 allow remote attackers to cause a denial of service (segmentation violation for read access, and application crash) by triggering an invalid Unicode property lookup.
