    CVE-2025-58050 (GCVE-0-2025-58050)

    Vulnerability from cvelistv5 – Published: 2025-08-27 18:47 – Updated: 2025-08-27 19:14

    Title
    PCRE2: heap-buffer-overflow read in match_ref due to missing boundary restoration in SCS
    Summary
    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 lead to information disclosure if the out-of-bounds data read during the memcmp affects the final match result in a way observable by the attacker. This issue has been resolved in version 10.46.
