SCA: security update for github.com/hamba/avro, github.com/hamba/avro/v2 (GHSA-9x44-9pgq-cf45)

high Tenable Self-Hosted Container Security Plugin ID 413534

Description

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

 - Hamba avro is a go lang encoder/decoder implementation of the avro codec specification. In affected
 versions a well-crafted string passed to avro's `github.com/hamba/avro/v2.Unmarshal()` can throw a `fatal
 error: runtime: out of memory` which is unrecoverable and can cause denial of service of the consumer of
 avro. The root cause of the issue is that avro uses part of the input to `Unmarshal()` to determine the
 size when creating a new slice and hence an attacker may consume arbitrary amounts of memory which in turn
 may cause the application to crash. This issue has been addressed in commit `b4a402f4` which has been
 included in release version `2.13.0`. Users are advised to upgrade. There are no known workarounds for
 this vulnerability. (CVE-2023-37475)
