A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.

Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1

Vulnerability in the Siebel UI Framework product of Oracle Siebel CRM (component: EAI, SWSE). Supported versions that are affected are 20.2 and prior. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Siebel UI Framework. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Siebel UI Framework accessible data. CVSS 3.0 Base Score 4.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N).

In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.

Vulnerability in the Siebel UI Framework product of Oracle Siebel CRM (component: SWSE Server). Supported versions that are affected are 19.10 and prior. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Siebel UI Framework. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Siebel UI Framework, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Siebel UI Framework accessible data. CVSS 3.0 Base Score 4.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N).

FasterXML jackson-databind 2.x before 2.9.10.2 lacks certain net.sf.ehcache blocking.

SubTypeValidator.java in FasterXML jackson-databind before 2.9.9.2 mishandles default typing when ehcache is used (because of net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), leading to remote code execution.
