critical Nessus Plugin ID 166561

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-5702-1 advisory.

 Robby Simpson discovered that curl incorrectly handled certain POST operations after PUT operations. This issue could cause applications using curl to send the wrong data, perform incorrect memory operations, or crash. (CVE-2022-32221)

 Hiroki Kurosawa discovered that curl incorrectly handled parsing .netrc files. If an attacker were able to provide a specially crafted .netrc file, this issue could cause curl to crash, resulting in a denial of service. This issue only affected Ubuntu 22.10. (CVE-2022-35260)

 It was discovered that curl incorrectly handled certain HTTP proxy return codes. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2022-42915)

 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-2022-42916)

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
