FreeBSD : newspost -- server response buffer overflow vulnerability (7f13607b-6948-11d9-8937-00065be4b5b6)

high Nessus Plugin ID 19001

Synopsis

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

Description

The newspost program uses a function named socket_getline to read server responses from the network socket. Unfortunately this function does not check the length of the buffer in which the read data is stored and only stops reading when a newline character is found.

A malicious NNTP server could use this bug to cause a buffer overflow by sending an overly long response. Such an overflow allows arbitrary code to be executed, with the privileges of the newspost process, on the affected systems.

Solution

Update the affected package.
