CVE-2017-7186

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.

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.

The compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE through 8.x before revision 1680 (e.g., the PHP 7.1.1 bundled version) allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted regular expression (CVE-2017-6004).

A vulnerability was found in pcre caused by trying to find a Unicode property for a code value greater than 0x10ffff, the Unicode maximum, when running in non-UTF mode (where character values can be up to 0xffffffff) (CVE-2017-7186).

The _pcre32_xclass function in pcre_xclass.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (invalid memory read) via a crafted file (CVE-2017-7244).

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 4) or possibly have unspecified other impact via a crafted file (CVE-2017-7245).

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 (CVE-2017-7246).

These are all security issues fixed in the libpcre1-32bit-8.45-1.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libpcre2-16-0-10.37-1.2 package on the GA media of openSUSE Tumbleweed.

This update for pcre fixes the following issues:

Update pcre to version 8.45:

• CVE-2020-14155: Fixed integer overflow via a large number after a '(?C' substring (bsc#1172974).
• CVE-2019-20838: Fixed buffer over-read in JIT compiler (bsc#1172973).
• CVE-2017-7244: Fixed invalid read in _pcre32_xclass() (bsc#1030807).
• CVE-2017-7245: Fixed buffer overflow in the pcre32_copy_substring (bsc#1030805).
• CVE-2017-7246: Fixed another buffer overflow in the pcre32_copy_substring (bsc#1030803).
• CVE-2017-7186: Fixed denial of service caused by an invalid Unicode property lookup (bsc#1030066).
• CVE-2017-6004: Fixed denial of service via crafted regular expression (bsc#1025709).

It was discovered that PCRE incorrectly handled certain regular expressions. A remote attacker could use this issue to cause applications using PCRE to crash, resulting in a denial of service. (CVE-2017-6004)
