Synopsis

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

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2813-1 advisory.

- libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation.
(CVE-2022-27781)

- libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily. (CVE-2022-27782)

- 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 curl, libcurl4 and / or libcurl4-32bit packages.
