high Nessus Plugin ID 161058

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-5412-1 advisory.

 Axel Chong discovered that curl incorrectly handled percent-encoded URL separators. A remote attacker could possibly use this issue to trick curl into using the wrong URL and bypass certain checks or filters.
 This issue only affected Ubuntu 22.04 LTS. (CVE-2022-27780)

 Florian Kohnhuser discovered that curl incorrectly handled returning a TLS server's certificate chain details. A remote attacker could possibly use this issue to cause curl to stop responding, resulting in a denial of service. (CVE-2022-27781)

 Harry Sintonen discovered that curl incorrectly reused a previous connection when certain options had been changed, contrary to expectations. (CVE-2022-27782)

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.
