Description SMASH SMASH 2023-10-11 06:50:16 UTC

Severity: important

Description:

Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially
crafted, invalid trailer header could cause Tomcat to treat a single
request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.

Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue.

Affected versions:

- Apache Tomcat 11.0.0-M1 through 11.0.0-M11
- Apache Tomcat 10.1.0-M1 through 10.1.13
- Apache Tomcat 9.0.0-M1 through 9.0.81
- Apache Tomcat 8.5.0 through 8.5.93

Comment 6 Michele Bussolotto 2023-10-30 14:20:53 UTC

Request for factory https://build.opensuse.org/request/show/1121149
As soon it will be accepted, it will be ported to 
- SUSE:SLE-15-SP2:Update/tomcat
- SUSE:ALP:Source:Standard:1.0/tomcat


Moreover, I had a look at SUSE:SLE-12-SP2:Update/tomcat and as far I understand from the code, version 8.0.53 is not affected
