| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2022-05-16 | CVE-2022-1586 | Out-of-bounds Read vulnerability in multiple products 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. | 9.1 |
| 2022-05-16 | CVE-2022-1587 | Out-of-bounds Read vulnerability in multiple products 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. | 9.1 |
| 2017-05-05 | CVE-2017-8786 | Improper Restriction of Operations within the Bounds of a Memory Buffer 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. | 9.8 |
| 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." | 9.8 |
| 2016-12-13 | CVE-2015-5073 | Information Exposure vulnerability in multiple products Heap-based buffer overflow in the find_fixedlength function in pcre_compile.c in PCRE before 8.38 allows remote attackers to cause a denial of service (crash) or obtain sensitive information from heap memory and possibly bypass the ASLR protection mechanism via a crafted regular expression with an excess closing parenthesis. | 9.1 |
| 2016-12-13 | CVE-2015-3210 | Out-of-bounds Write vulnerability in Pcre and Pcre2 Heap-based buffer overflow in PCRE 8.34 through 8.37 and PCRE2 10.10 allows remote attackers to execute arbitrary code via a crafted regular expression, as demonstrated by /^(?P=B)((?P=B)(?J:(?P<B>c)(?P<B>a(?P=B)))>WGXCREDITS)/, a different vulnerability than CVE-2015-8384. | 9.8 |
| 2016-03-17 | CVE-2016-3191 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Pcre 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 demonstrated by a JavaScript RegExp object encountered by Konqueror, aka ZDI-CAN-3542. | 9.8 |
| 2016-01-03 | CVE-2016-1283 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products 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 unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. | 9.8 |
| 2015-12-02 | CVE-2015-8394 | Integer Overflow or Wraparound vulnerability in multiple products PCRE before 8.38 mishandles the (?(<digits>) and (?(R<digits>) conditions, which allows remote attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. | 9.8 |
| 2015-12-02 | CVE-2015-8391 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The pcre_compile function in pcre_compile.c in PCRE before 8.38 mishandles certain [: nesting, which allows remote attackers to cause a denial of service (CPU consumption) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. | 9.8 |
