Description

This security bulletin contains information about 1 security vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2025-58050)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the PCRE2 regular expression matching engine during handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. A remote attacker can pass specially crafted input to the application, trigger an out-of-bounds read error and read contents of memory on the system.
