Synopsis

ulogd contains a possible buffer overflow potentially allowing for the remote execution of arbitrary code.

2. Impact Information

Background

ulogd is a userspace daemon for netfilter related logging.

Description

SUSE reported unspecified buffer overflows in ulogd involving the calculation of string lengths.

Impact

A remote attacker could trigger a possible buffer overflow through unspecified vectors, potentially leading to the remote execution of arbitrary code with the rights of the user running the ulogd daemon, or more probably leading to the crash of the daemon.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All ulogd users should upgrade to the latest version:
