openSUSE 15 Security Update : nim (openSUSE-SU-2021:1585-1)

critical Nessus Plugin ID 156138

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SUSE15 host has a package installed that is affected by a vulnerability as referenced in the openSUSE-SU-2021:1585-1 advisory.

- Nim is a systems programming language with a focus on efficiency, expressiveness, and elegance. In affected versions the uri.parseUri function which may be used to validate URIs accepts null bytes in the input URI. This behavior could be used to bypass URI validation. For example:
parseUri(http://localhost\0hello).hostname is set to localhost\0hello. Additionally, httpclient.getContent accepts null bytes in the input URL and ignores any data after the first null byte.
Example: getContent(http://localhost\0hello) makes a request to localhost:80. An attacker can use a null bytes to bypass the check and mount a SSRF attack. (CVE-2021-41259)

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 nim package.
