Ubuntu 17.10 / 18.04 LTS : curl vulnerability (USN-3710-1)

High Nessus Plugin ID 111038

Synopsis

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

Description

Peter Wu discovered that curl incorrectly handled certain SMTP buffers. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code.

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 packages.
