Description Mauro Matteo Cascella 2022-07-18 15:29:05 UTC
As per samba upstream advisory:

Due to incorrect values used as the limit for a loop and as the 'count' parameter to memcpy(), the server, receiving a specially crafted message, leaves an array of structures partially uninitialized, or accesses an arbitrary element beyond the end of an array.

Outcomes achievable by an attacker include segmentation faults and corresponding loss of availability. Depending on the contents of the uninitialized memory, confidentiality may also be affected.
