Arch Linux Security Advisory ASA-201908-10

Severity: High
Date    : 2019-08-16
CVE-ID  : CVE-2018-11782 CVE-2019-0203
Package : subversion
Type    : denial of service
Remote  : Yes
Link    : https://security.archlinux.org/AVG-1016


The package subversion before version 1.12.2-1 is vulnerable to denial
of service.


Upgrade to 1.12.2-1.

# pacman -Syu "subversion>=1.12.2-1"

The problems have been fixed upstream in version 1.12.2.




- CVE-2018-11782 (denial of service)

Subversion svn:// connections, including svn+ssh:// and
svn+<custom>://, use a custom network protocol [1] with Lisp-like
syntax. The code implementing the protocol has dedicated codepaths for
serialization of revision numbers into protocol integers.  A particular
client query could cause the server to attempt to reply with a revision
number whose value is the invalid revision number constant
`SVN_INVALID_REVNUM`, thereby triggering an assertion failure in the
the serialization layer.

- CVE-2019-0203 (denial of service)

A null-pointer-dereference has been found in svnserve that results in a
remote unauthenticated Denial-of-Service in some server configurations.
The vulnerability can be triggered by an unauthenticated user if the
server is configured with anonymous access enabled.


A remote attacker is able to cause a denial of service by sending a
special packet.
