Fedora 26: 2017-704c201dbb Moderate: Subversion Memory Collision Attack

Subversion is a concurrent version control system which enables one

or more users to collaborate in developing and maintaining a

hierarchy of files and directories while keeping a history of all

changes. Subversion only stores the differences between versions,

instead of every complete file. Subversion is intended to be a

compelling replacement for CVS.

This update includes the latest stable release of _Apache Subversion_, version

**1.9.6**. ### User-visible changes: #### Client-side bugfixes: * cp/mv:

improve error message when target is an unversioned dir * merge: reduce memory

usage with large amounts of mergeinfo ([issue

4667]()) #### Server-side

bugfixes: * 'svnadmin freeze': document the purpose more clearly * dump: fix

segfault when a revision has no revprops * fsfs: improve error message upon

failure to open rep-cache * fsfs: never attempt to share directory

representations * fsfs: make consistency independent of hash algorithms

This change makes Subversion resilient to collision attacks, including

SHA-1 collision attacks such as See also our

documentation at https://subversion.apache.org/faq#shattered-sha1 and

https://subversion.apache.org/docs/release-notes/1.9#shattered-sha1. ####

Client-side and server-side bugfixes: * work around an APR bug related to file

truncation #### Bindings bugfixes: * javahl: follow redirects when opening a

connection
