FreeBSD : libzmq4 -- Remote Code Execution Vulnerability (8e48365a-214d-11e9-9f8a-0050562a4d7b)

high Nessus Plugin ID 121405

Language:

Synopsis

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

Description

A vulnerability has been found that would allow attackers to direct a peer to jump to and execute from an address indicated by the attacker.
This issue has been present since v4.2.0. Older releases are not affected.

NOTE: The attacker needs to know in advance valid addresses in the peer's memory to jump to, so measures like ASLR are effective mitigations.

NOTE: this attack can only take place after authentication, so peers behind CURVE/GSSAPI are not vulnerable to unauthenticated attackers.

Solution

Update the affected package.
