Important: pcre2 security update
The pcre2 package contains a new generation of the Perl Compatible Regular Expression libraries for implementing regular expression pattern matching using the same syntax and semantics as Perl. Security Fix(es): * pcre2: PCRE2: Out-of-bounds write allows arbitrary code execution via crafted regular expressions (CVE-2026-86145) * pcre2: PCRE2: Out-of-bounds write via large pattern input (CVE-2026-89157) * PCRE2: PCRE2: Out-of-bounds write via integer overflow on 32-bit platforms (CVE-2026-89158) * pcre2: pcre2: Out-of-bounds write via crafted regular expression (CVE-2026-103111) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
