Synopsis

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

Description

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3868-1 advisory.

- An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage will take significant time to parse. (CVE-2022-32149)

- A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests. (CVE-2022-41723)

- Prometheus Exporter Toolkit is a utility package to build exporters. Prior to versions 0.7.2 and 0.8.2, if someone has access to a Prometheus web.yml file and users' bcrypted passwords, they can bypass security by poisoning the built-in authentication cache. Versions 0.7.2 and 0.8.2 contain a fix for the issue. There is no workaround, but attacker must have access to the hashed password to use this functionality.
(CVE-2022-46146)

- Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable. (CVE-2023-29409)

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.
