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.
