Debian DSA-3932-1 : subversion - security update

critical Nessus Plugin ID 102372

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several problems were discovered in Subversion, a centralised version control system.

- CVE-2016-8734 (jessie only)

Subversion's mod_dontdothat server module and Subversion clients using http(s):// were vulnerable to a denial-of-service attack caused by exponential XML entity expansion.

- CVE-2017-9800 Joern Schneeweisz discovered that Subversion did not correctly handle maliciously constructed svn+ssh:// URLs. This allowed an attacker to run an arbitrary shell command, for instance via svn:externals properties or when using 'svnsync sync'.

Solution

Upgrade the subversion packages.

For the oldstable distribution (jessie), these problems have been fixed in version 1.8.10-6+deb8u5.

For the stable distribution (stretch), these problems have been fixed in version 1.9.5-1+deb9u1.
