Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS

Summary:

An attacker could send crafted input to the Subversion mod_dav_svn module for Apache and cause it to crash or gain access to restricted files.

Software Description: - subversion: Advanced version control system

Details:

Joe Schaefer discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain baselined WebDAV resource requests. A remote attacker could use this flaw to cause the service to crash, leading to a denial of service. (CVE-2011-1752)

Ivan Zhakov discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain requests. A remote attacker could use this flaw to cause the service to consume all available resources, leading to a denial of service. (CVE-2011-1783)

Kamesh Jayachandran discovered that the Subversion mod_dav_svn module for Apache did not properly handle access control in certain situations. A remote user could use this flaw to gain access to files that would otherwise be unreadable. (CVE-2011-1921)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04:
libapache2-svn 1.6.12dfsg-4ubuntu2.1

Ubuntu 10.10:
libapache2-svn 1.6.12dfsg-1ubuntu1.3

Ubuntu 10.04 LTS:
libapache2-svn 1.6.6dfsg-2ubuntu1.3

After a standard system update you need to restart any applications that use Subversion, such as Apache when using mod_dav_svn, to make all the necessary changes.

Title: Apache Subversion vulnerability 1.5.x and 1.6.x before 1.6.17 in VisualSVN Server (CVE-2011-1783)
Description: The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is enabled, allows remote attackers to cause a denial of service (infinite loop and memory consumption) in opportunistic circumstances by requesting data.

Description: The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is disabled, does not properly enforce permissions for files that had been publicly readable in the past, which allows remote attackers to obtain sensitive information via a replay REPORT operation.
