Description

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

This release serves as a replacement for Red Hat JBoss Enterprise
Application Platform 6.1.0, and includes bug fixes and enhancements. Refer
to the 6.1.1 Release Notes for information on the most significant of these
changes, available shortly from
https://access.redhat.com/site/documentation/

Security fixes:

Cross-site scripting (XSS) flaws were found in the mod_info, mod_status,
mod_imagemap, mod_ldap, and mod_proxy_ftp modules. An attacker could
possibly use these flaws to perform XSS attacks if they were able to make
the victim's browser generate an HTTP request with a specially-crafted Host
header. (CVE-2012-3499)

Cross-site scripting (XSS) flaws were found in the mod_proxy_balancer
module's manager web interface. If a remote attacker could trick a user,
who was logged into the manager web interface, into visiting a
specially-crafted URL, it would lead to arbitrary web script execution in
the context of the user's manager interface session. (CVE-2012-4558)

A flaw was found in the way the mod_dav module handled merge requests. An
attacker could use this flaw to send a crafted merge request that contains
URIs that are not configured for DAV, causing the httpd child process to
crash. (CVE-2013-1896)

A flaw was found in the way Apache Santuario XML Security for Java
validated XML signatures. Santuario allowed a signature to specify an
arbitrary canonicalization algorithm, which would be applied to the
SignedInfo XML fragment. A remote attacker could exploit this to spoof an
XML signature via a specially-crafted XML signature block. (CVE-2013-2172)

It was found that mod_rewrite did not filter terminal escape sequences from
its log file. If mod_rewrite was configured with the RewriteLog directive,
a remote attacker could use specially-crafted HTTP requests to inject
terminal escape sequences into the mod_rewrite log file. If a victim viewed
the log file with a terminal emulator, it could result in arbitrary command
execution with the privileges of that user. (CVE-2013-1862)

The data file used by PicketBox Vault to store encrypted passwords contains
a copy of its own admin key. The file is encrypted using only this admin
key, not the corresponding JKS key. A local attacker with permission to
read the vault data file could read the admin key from the file, and use it
to decrypt the file and read the stored passwords in clear text.
(CVE-2013-1921)

A flaw was found in JGroup's DiagnosticsHandler that allowed an attacker on
an adjacent network to reuse the credentials from a previous successful
authentication. This could be exploited to read diagnostic information
(information disclosure) and attain limited remote code execution.
(CVE-2013-4112)
