Rocky Linux 8 : curl (RLSA-2022:6159)

medium Nessus Plugin ID 164490

Synopsis

The remote Rocky Linux host is missing one or more security updates.

Description

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:6159 advisory.

 - curl < 7.84.0 supports chained HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable links in this decompression chain was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a malloc bomb, makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors. (CVE-2022-32206)

 - When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly.
 This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client. (CVE-2022-32208)

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.
