This security bulletin contains information about 3 secuirty vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2025-15467)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing CMS AuthEnvelopedData structures that use AEAD ciphers such as AES-GCM, the IV (Initialization Vector) encoded in the ASN.1 parameters. A remote attacker can supply a specially crafted CMS message with an oversized IV, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

3) Integer overflow (CVE-ID: CVE-2025-13601)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to integer overflow within the g_escape_uri_string() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service attack.
