A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages.

A flaw was found in Apache Tomcat, where an h2c direct connection did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests are made, an OutOfMemoryException could occur, leading to a denial of service. The highest threat from this vulnerability is to system availability.

RHSA-2020:4004
Vulnerability from csaf_redhat - Published: 2020-09-29 19:54 - Updated: 2026-06-25 10:56It was found that tomcat's FORM authentication allowed a very small period in which an attacker could possibly force a victim to use a valid user session, or Session Fixation. While practical exploit of this issue is deemed highly improbable, an abundance of caution merits it be considered a flaw. The highest threat from this vulnerability is to system availability, but also threatens data confidentiality and integrity.

A flaw was found in Apache Tomcat, where the payload length in a WebSocket frame was not correctly validated. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. The highest threat from this vulnerability is to system availability.

RHSA-2020_3303
Vulnerability from csaf_redhat - Published: 2020-08-04 11:18 - Updated: 2024-12-08 11:37A flaw was found in Apache Tomcat. The HTTP header parsing code used an approach to end-of-line (EOL) parsing that allowed some invalid HTTP headers to be parsed as valid. This led to the 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. The highest threat with this vulnerability is system availability.

RHSA-2020_3305
Vulnerability from csaf_redhat - Published: 2020-08-04 11:17 - Updated: 2024-12-08 11:37A flaw was found in Apache Tomcat. The HTTP header parsing code used an approach to end-of-line (EOL) parsing that allowed some invalid HTTP headers to be parsed as valid. This led to the 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. The highest threat with this vulnerability is system availability.
