NVD Description

Note: Versions mentioned in the description apply only to the upstream libndr-nbt-devel package and not the libndr-nbt-devel package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity.
