Description
This security bulletin contains information about 4 secuirty vulnerabilities.

3) Out-of-bounds read (CVE-ID: CVE-2022-29458)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in convert_strings in tinfo/read_entry.c in the terminfo library. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
4) Double free (CVE-ID: CVE-2025-8058)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the regcomp() function in case previous memory allocations fail. A remote attacker can pass specially crafted data to the application, trigger double free error and execute arbitrary code on the target system.
