medium Nessus Plugin ID 306042
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- When calling base64.b64decode() or related functions the decoding process would stop after encountering the first padded quad regardless of whether there was more information to be processed. This can lead to data being accepted which may be processed differently by other implementations. Use validate=True to enable stricter processing of base64 data. (CVE-2026-3446)
Note that Nessus relies on the presence of the package as reported by the vendor.
