Ubuntu 22.04 LTS : curl regression (USN-6237-2)

info Nessus Plugin ID 178486

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6237-2 advisory.

 USN-6237-1 fixed vulnerabilities in curl. The update caused a certificate wildcard handling regression on Ubuntu 22.04 LTS. This update fixes the problem.

 We apologize for the inconvenience.

 Original advisory details:

 Hiroki Kurosawa discovered that curl incorrectly handled validating certain

 certificate wildcards. A remote attacker could possibly use this issue to

 spoof certain website certificates using IDN hosts. (CVE-2023-28321)

 Hiroki Kurosawa discovered that curl incorrectly handled callbacks when

 certain options are set by applications. This could cause applications

 using curl to misbehave, resulting in information disclosure, or a denial

 of service. (CVE-2023-28322)

 It was discovered that curl incorrectly handled saving cookies to files. A

 local attacker could possibly use this issue to create or overwrite files.

 This issue only affected Ubuntu 22.10, and Ubuntu 23.04. (CVE-2023-32001)

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

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

Solution

Update the affected packages.
