CVE-2015-0202

Updated subversion packages fix security vulnerabilities:

Subversion HTTP servers with FSFS repositories are vulnerable to a remotely triggerable excessive memory use with certain REPORT requests (CVE-2015-0202).

Subversion mod_dav_svn and svnserve are vulnerable to a remotely triggerable assertion DoS vulnerability for certain requests with dynamically evaluated revision numbers (CVE-2015-0248).

Subversion HTTP servers allow spoofing svn:author property values for new revisions (CVE-2015-0251).

These are all security issues fixed in the libsvn_auth_gnome_keyring-1-0-1.9.5-1.1 package on the GA media of openSUSE Tumbleweed.

Apache Subversion was updated to fix three vulnerabilities.

The following vulnerabilities were fixed:

• Subversion HTTP servers with FSFS repositories were vulnerable to a remotely triggerable excessive memory use with certain REPORT requests. (bsc#923793 CVE-2015-0202)
• Subversion mod_dav_svn and svnserve were vulnerable to a remotely triggerable assertion DoS vulnerability for certain requests with dynamically evaluated revision numbers. (bsc#923794 CVE-2015-0248)
• Subversion HTTP servers allow spoofing svn:author property values for new revisions (bsc#923795 CVE-2015-0251)

• make the subversion package conflict with KWallet and Gnome Keyring packages with do not require matching subversion versions in SLE 12 and openSUSE Leap 42.1 and thus break the main package upon partial upgrade. (bsc#969159)

• CVE-2015-5343: Remotely triggerable heap overflow and out-of-bounds read in mod_dav_svn caused by integer overflow when parsing skel-encoded request bodies. (bsc#958300)

• CVE-2015-3184: mod_authz_svn: mixed anonymous/authenticated httpd (dav) configurations could lead to information leak (bsc#939514)

• CVE-2015-3187: do not leak paths that were hidden by path-based authz (bsc#939517)

• CVE-2015-0202: Subversion HTTP servers with FSFS repositories were vulnerable to a remotely triggerable excessive memory use with certain REPORT requests. (bsc#923793)

• CVE-2015-0248: Subversion mod_dav_svn and svnserve were vulnerable to a remotely triggerable assertion DoS vulnerability for certain requests with dynamically evaluated revision numbers. (bsc#923794)

• CVE-2015-0251: Subversion HTTP servers allow spoofing svn:author property values for new revisions (bsc#923795)

• fix sample configuration comments in subversion.conf (bsc#916286)

• fix sysconfig file generation (bsc#911620)

• CVE-2014-3580: mod_dav_svn invalid REPORT requests could lead to denial of service (bsc#909935)

• CVE-2014-8108: mod_dav_svn use of invalid transaction names could lead to denial of service (bsc#909935)

• INSTALL#SQLite says 'Subversion 1.8 requires SQLite version 3.7.12 or above'; therefore I lowered the sqlite requirement to make the subversion run on older system versions, tooi. [bsc#897033]

The mod_dav_svn server in Subversion 1.8.0 through 1.8.11 allows remote attackers to cause a denial of service (memory consumption) via a large number of REPORT requests, which trigger the traversal of FSFS repository nodes.

It was discovered that the Subversion mod_dav_svn module incorrectly handled REPORT requests for a resource that does not exist. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3580)

It was discovered that the Subversion mod_dav_svn module incorrectly handled requests requiring a lookup for a virtual transaction name that does not exist. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-8108)

Evgeny Kotkov discovered that the Subversion mod_dav_svn module incorrectly handled large numbers of REPORT requests. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-0202)

Evgeny Kotkov discovered that the Subversion mod_dav_svn and svnserve modules incorrectly certain crafted parameter combinations. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. (CVE-2015-0248)

Ivan Zhakov discovered that the Subversion mod_dav_svn module incorrectly handled crafted v1 HTTP protocol request sequences. A remote attacker could use this issue to spoof the svn:author property. (CVE-2015-0251)

C. Michael Pilato discovered that the Subversion mod_dav_svn module incorrectly restricted anonymous access. A remote attacker could use this issue to read hidden files via the path name. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-3184)

C. Michael Pilato discovered that Subversion incorrectly handled path-based authorization. A remote attacker could use this issue to obtain sensitive path information. (CVE-2015-3187)
