An update for pcre2 is now available for openEuler-24.03-LTS-SP4,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-4111 Final 1.0 1.0 2026-09-25 Initial 2026-09-25 2026-09-25 openEuler SA Tool V1.0 2026-09-25 pcre2 security update An update for pcre2 is now available for openEuler-24.03-LTS-SP4,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP3 PCRE2 is a re-working of the original PCRE1 library to provide an entirely new API. Since its initial release in 2015, there has been further development of the code and it now differs from PCRE1 in more than just the API. PCRE2 is written in C, and it has its own API. There are three sets of functions, one for the 8-bit library, which processes strings of bytes, one for the 16-bit library, which processes strings of 16-bit values, and one for the 32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there are no C++ wrappers. Security Fix(es): PCRE2 before 10.48 has a pcre2_match out-of-bounds read after a JIT fallback when an attacker can provide invalid UTF data.(CVE-2026-89156) PCRE2 before 10.48, on 32-bit platforms, has a pcre2_pattern_convert out-of-bounds write when an attacker can provide a large pattern.(CVE-2026-89157) PCRE2 before 10.48, on 32-bit platforms, has a pcre2_compile_32 integer overflow and resultant out-of-bounds write.(CVE-2026-89158) PCRE2 before 10.48 has a pcre2_match out-of-bounds read during the PCRE2_MATCH_INVALID_UTF matching of an invalid UTF subject.(CVE-2026-89160) In PCRE2 before 10.48, pcre2_jit_match mishandles a previously copied subject being passed in as a context. An incorrect free operation can occur.(CVE-2026-89161) An update for pcre2 is now available for openEuler-24.03-LTS-SP4,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high.
