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 :
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
