Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : curl vulnerabilities (USN-5788-1)

high Nessus Plugin ID 169585

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5788-1 advisory.

 Hiroki Kurosawa discovered that curl incorrectly handled HSTS support when certain hostnames included IDN characters. A remote attacker could possibly use this issue to cause curl to use unencrypted connections.
 This issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2022-43551)

 It was discovered that curl incorrectly handled denials when using HTTP proxies. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2022-43552)

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 packages.
