Description

A NULL pointer dereference flaw was found in the way the mod_dav_svn module processed certain requests to lock working copy paths in a repository. A remote attacker could issue a lock request that could cause the httpd process serving the request to crash. (CVE-2011-0715)

The Fedora Project would like to thank Hyrum Wright of the Apache Subversion project for reporting this issue. Upstream acknowledges Philip Martin, WANdisco, Inc. as the original reporter.

Several bugs are also fixed in this update :

Several bugs are also fixed in this update :

  - more improvement to the 'blame -g' memory leak from
    1.6.15

    - avoid unnecessary globbing for performance

    - don't add tree conflicts when one already exists

    - fix potential crash when requesting mergeinfo

    - don't attempt to resolve prop conflicts in 'merge
      --dry-run'

    - improve svnsync handling of dir copies

    - hide unreadable dirs in mod_dav_svn's GET response

    - make 'svnmucc propsetf' actually work

    - limit memory fragmentation in svnserve

    - fix 'svn export' regression from 1.6.13

    - fix 'svn export' mistakenly uri-encodes paths

    - fix server-side memory leaks triggered by 'blame -g'

    - prevent crash in mod_dav_svn when using SVNParentPath

    - allow 'log -g' to continue in the face of invalid
      mergeinfo

    - filter unreadable paths for 'svn ls' and 'svn co'

    - fix abort in 'svn blame -g'

    - fix file handle leak in ruby bindings

    - remove check for 1.7-style working copies
