fkie_cve-2026-5358

Rejected reason: REJECTED: CVE-2026-5358 is rejected for two reasons. Firstly it has been discovered that no NIS+ client or server was ever released for any Linux-based OS distributions and as such this makes the API provisional and unused. Secondly it has been discovered that the NIS+ cold start cache (/var/nis/NIS_COLD_START) cannot be bypassed and as such the API can only be called with a trusted server from the pre-populated cache. The use of a trusted server means no trust boundary is crossed and this is therefore considered a normal bug.

The obsolete nis_local_principal function in the GNU C Library version 2.43 and older may overflow a buffer in the data section, which could allow an attacker to spoof a crafted response to a UDP request generated by this function and overwrite neighboring static data in the requesting application.

NIS support is obsolete and has been deprecated in the GNU C Library since version 2.26 and is only maintained for legacy usage. Applications should port away from NIS to more modern identity and access management services.
