Description

It was discovered that PostgreSQL did not properly handle encoding conversion failures. An attacker could exploit this by sending specially crafted requests to PostgreSQL, leading to a denial of service.

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.
