Description
This security bulletin contains information about 4 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2025-11187)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when parsing PKCS#12 files. A remote attacker can pass a specially crafted PKCS#12 file to the application, trigger a stack-based buffer overflow and perform a denial of service attack.
2) Stack-based buffer overflow (CVE-ID: CVE-2025-15467)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber
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.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) NULL pointer dereference (CVE-ID: CVE-2025-15468)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the SSL_CIPHER_find() function. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
4) Use-after-free (CVE-ID: CVE-2026-45447)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to use-after-free in the PKCS7_verify() function when processing a specially crafted PKCS#7 or S/MIME signed message during PKCS#7 signature verification. A remote attacker can send a specially crafted signed message to execute arbitrary code.
Applications using the CMS APIs for this processing are not affected.
