Description Jan Lieskovsky 2013-06-03 10:24:17 UTC

A security flaw was found in the way FSFS repository format functionality of Subversion, a concurrent version control system, processed filenames containing newline (ASCII 0x0a) character sequence. Remote attacker (via malicious client) could commit a revision for the FSFS repository, containing specially-crafted content that in subsequent requests could lead to disruption of the service of that repository for other users.
