www-servers/tomcat	*	< 8.5.60:8.5, < 9.0.40:9	>= 8.5.60:8.5, >= 9.0.40:9

Background

Apache Tomcat is a Servlet-3.0/JSP-2.2 Container.

Description

It was discovered that Apache Tomcat could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream.

Background

Apache Tomcat is a Servlet-3.0/JSP-2.2 Container.

Description

Multiple vulnerabilities have been discovered in Apache Tomcat. Please review the CVE identifiers referenced below for details.

Impact

The vulnerabilities allow an attacker to cause a Denial of Service, to hijack a session, to bypass authentication, to inject webscript, to enumerate valid usernames, to read, modify and overwrite arbitrary files, to bypass intended access restrictions, to delete work-directory files, to discover the server’s hostname or IP, to bypass read permissions for files or HTTP headers, to read or write files outside of the intended working directory, and to obtain sensitive information by reading a log file.

Workaround

There is no known workaround at this time.

Resolution

All Apache Tomcat 6.0.x users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-6.0.35"

All Apache Tomcat 7.0.x users should upgrade to the latest version:

Advisory

Affected packages

Package	Arch	Vulnerable	Unaffected
www-servers/tomcat	*	< 6.0.16	>= 5.5.26 (revision), >= 6.0.16, >= 5.5.27 (revision)

Background

Tomcat is the Apache Jakarta Project's official implementation of Java Servlets and Java Server Pages.

Description

The following vulnerabilities were reported:

• Delian Krustev discovered that the JULI logging component does not properly enforce access restrictions, allowing web application to add or overwrite files (CVE-2007-5342).
• When the native APR connector is used, Tomcat does not properly handle an empty request to the SSL port, which allows remote attackers to trigger handling of a duplicate copy of one of the recent requests (CVE-2007-6286).
• If the processing or parameters is interrupted, i.e. by an exception, then it is possible for the parameters to be processed as part of later request (CVE-2008-0002).
• An absolute path traversal vulnerability exists due to the way that WebDAV write requests are handled (CVE-2007-5461).
• Tomcat does not properly handle double quote (") characters or %5C (encoded backslash) sequences in a cookie value, which might cause sensitive information such as session IDs to be leaked to remote attackers and enable session hijacking attacks (CVE-2007-5333).

Impact

These vulnerabilities can be exploited by:

• a malicious web application to add or overwrite files with the permissions of the user running Tomcat.
• a remote attacker to conduct session hijacking or disclose sensitive data.

Workaround

There is no known workaround at this time.

Resolution

All Tomcat 5.5.x users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-5.5.26"

All Tomcat 6.0.x users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-6.0.16"

Affected packages

Package	Arch	Vulnerable	Unaffected
www-servers/tomcat	*	< 5.5.22	>= 5.5.22

Background

Tomcat is the Apache Jakarta Project's official implementation of Java Servlets and Java Server Pages.

Description

Tomcat allows special characters like slash, backslash or URL-encoded backslash as a separator, while Apache does not.

Impact

A remote attacker could send a specially crafted URL to the vulnerable Tomcat server, possibly resulting in a directory traversal and read access to arbitrary files with the privileges of the user running Tomcat. Note that this vulnerability can only be exploited when using apache proxy modules like mod_proxy, mod_rewrite or mod_jk.

Workaround

There is no known workaround at this time.

Resolution

All Tomcat users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-5.5.22"

Bugs

#59232

Advisory

https://security.gentoo.org/glsa/200408-15

Affected packages

Package	Arch	Vulnerable	Unaffected
www-servers/tomcat	*	< 5.0.27-r3	>= 5.0.27-r3, >= 4.1.30-r4 (revision), >= 3.3.2-r2 (revision)

Background

Tomcat is the Apache Jakarta Project's official implementation of Java Servlets and Java Server Pages.

Description

The Gentoo ebuild for Tomcat sets the ownership of the Tomcat init scripts as tomcat:tomcat, but those scripts are executed with root privileges when the system is started. This may allow a member of the tomcat group to run arbitrary code with root privileges when the Tomcat init scripts are run.

Impact

This could lead to a local privilege escalation or root compromise by authenticated users.

Workaround

Users may change the ownership of /etc/init.d/tomcat* and /etc/conf.d/tomcat* to be root:root:

# chown -R root:root /etc/init.d/tomcat*
# chown -R root:root /etc/conf.d/tomcat*

Resolution

All Tomcat users can upgrade to the latest stable version, or simply apply the workaround:

# emerge sync
# emerge -pv ">=www-servers/tomcat-5.0.27-r3"
# emerge ">=www-servers/tomcat-5.0.27-r3"
