The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2024:6908 advisory.
* net/http: Denial of service due to improper 100-continue handling in net/http (CVE-2024-24791)
* go/parser: golang: Calling any of the Parse functions containing deeply nested literals can cause a panic/stack exhaustion (CVE-2024-34155)
* encoding/gob: golang: Calling Decoder.Decode on a message which contains deeply nested structures can cause a panic due to stack exhaustion (CVE-2024-34156)
* go/build/constraint: golang: Calling Parse on a // +build build tag line with deeply nested expressions can cause a panic due to stack exhaustion (CVE-2024-34158)
Tenable has extracted the preceding description block directly from the AlmaLinux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
