NVD Description
Note: Versions mentioned in the description apply only to the upstream libsamba-util0-32bit package and not the libsamba-util0-32bit package as distributed by SLES.
See How to fix? for SLES:15.1 relevant fixed versions and status.
There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer.
