SCA: security update for github.com/russellhaering/gosaml2 (GHSA-6gc3-crp7-25w5)

medium Tenable Cloud Security Plugin ID 411430

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - gosaml2 is a Pure Go implementation of SAML 2.0. SAML Service Providers using this library for SAML
 authentication support are likely susceptible to Denial of Service attacks. A bug in this library enables
 attackers to craft a `deflate`-compressed request which will consume significantly more memory during
 processing than the size of the original request. This may eventually lead to memory exhaustion and the
 process being killed. The maximum compression ratio achievable with `deflate` is 1032:1, so by limiting
 the size of bodies passed to gosaml2, limiting the rate and concurrency of calls, and ensuring that lots
 of memory is available to the process it _may_ be possible to help Go's garbage collector "keep up".
 Implementors are encouraged not to rely on this. This issue is fixed in version 0.9.0. (CVE-2023-26483)
