USN-279-1: libnasl/nessus vulnerability

Releases

• Ubuntu 5.10
• Ubuntu 5.04

Details

Jayesh KS discovered that the nasl_split() function in the NASL
(Nessus Attack Scripting Language) library did not check for a
zero-length separator argument, which lead to an invalid memory
allocation. This library is primarily used in the Nessus security
scanner; a remote attacker could exploit this vulnerability to cause
the Nessus daemon to crash.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 5.10

• libnasl2 -

Ubuntu 5.04

• libnasl2 -

In general, a standard system update will make all the necessary changes.
