USN-8414-2

USN-8414-1 fixed several vulnerabilities in OpenSSL. This update provides the corresponding update for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS.

Original advisory details:

Frank Buss discovered that OpenSSL had a heap buffer over-read in ASN.1 content parsing. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or obtain sensitive information. (CVE-2026-34180)

Asim Viladi Oglu Manizada and Alex Gaynor discovered that OpenSSL could accept forged CMS AuthEnvelopedData messages. An attacker could possibly use this issue to bypass message authentication checks. (CVE-2026-34182)

Mayank Jangid, Kushal Khemka, Hari Priandana, Bhabani Sankar Das, and Qifan Zhang discovered that OpenSSL had a possible NULL dereference in password- based CMS decryption. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2026-42766)

Zhanpeng Liu, Guannan Wang, and Guancheng Li discovered that OpenSSL had a NULL pointer dereference in CRMF EncryptedValue decryption. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2026-42767)

Thai Duong discovered that OpenSSL had a heap use-after-free in PKCS7_verify(). An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-45447)

Zehua Qiao and Jinwen He discovered that OpenSSL had a possible heap buffer overflow in ASN.1 multibyte string conversion. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-7383)

Bhabani Sankar Das discovered that OpenSSL had an out-of-bounds read in CMS password-based decryption. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2026-9076)
