It was discovered that Tomcat did not properly limit the size of
WebDAV LOCK and PROPFIND request bodies. A remote attacker could
use this issue to cause Tomcat to consume excessive memory,
resulting in a denial of service. (CVE-2026-41284)
It was discovered that Tomcat incorrectly validated HTTP/2 header
fields. A remote attacker could use this issue to cause Tomcat to
crash or possibly execute arbitrary code. (CVE-2026-41293)
It was discovered that Tomcat did not properly clear HTTP
authentication headers during WebSocket connection upgrades and
redirects. A remote attacker could use this issue to obtain
sensitive credentials. (CVE-2026-42498)
It was discovered that Tomcat incorrectly handled digest
authentication. A remote attacker could possibly use this issue to
bypass authentication restrictions. (CVE-2026-43512)
It was discovered that Tomcat incorrectly handled case sensitivity
in LockOutRealm. A remote attacker could possibly use this issue to
bypass account lockout protections and obtain sensitive information.
(CVE-2026-43513)
It was discovered that Tomcat incorrectly handled authorization
when multiple method constraints defined the same HTTP method. A
remote attacker could possibly use this issue to bypass
authorization restrictions. (CVE-2026-43515)

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)
