CentOS Errata and Security Advisory CESA-2017:2480

Subversion (SVN) 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.

Security Fix(es):

  • A shell command injection flaw related to the handling of “svn+ssh” URLs has been discovered in Subversion. An attacker could use this flaw to execute shell commands with the privileges of the user running the Subversion client, for example when performing a “checkout” or “update” action on a malicious repository, or a legitimate repository containing a malicious commit. (CVE-2017-9800)

Red Hat would like to thank the Subversion Team for reporting this issue.
