Ubuntu 5.04 / 5.10 : libnasl vulnerability (USN-279-1)

Ubuntu Security Notice (C) 2006-2017 Canonical, Inc. / NASL script (C) 2006-2017 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected libnasl-dev and / or libnasl2 packages.

Risk factor :

Low / CVSS Base Score : 2.6
(CVSS2#AV:N/AC:H/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 2.1
(CVSS2#E:F/RL:OF/RC:ND)
Public Exploit Available : true
