Ubuntu 20.04 LTS / 26.04 LTS : SQL parse vulnerabilities (USN-8808-1)

high Nessus Plugin ID 349785

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8808-1 advisory.

 It was discovered that SQL parse contained multiple algorithmic complexity flaws when parsing SQL statements with deeply nested parentheses, comments, or dollar-quoted string literals. An attacker could use this issue to cause SQL parse to consume excessive CPU resources, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected pypy-sqlparse, python3-sqlparse and / or sqlformat packages.
