Debian DSA-2760-1 : chrony - several vulnerabilities

medium Nessus Plugin ID 69960

Language:

Synopsis

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

Description

Florian Weimer discovered two security problems in the Chrony time synchronisation software (buffer overflows and use of uninitialised data in command replies).

Solution

Upgrade the chrony packages.

For the oldstable distribution (squeeze), these problems will be fixed soon in 1.24-3+squeeze1 (due to a technical restriction in the archive processing scripts the two updates cannot be released together).

For the stable distribution (wheezy), these problems have been fixed in version 1.24-3.1+deb7u2.
