Summary
There is a limited write heap buffer overflow in the GSSAPI unwrap_des()
and unwrap_des3() routines of Heimdal (included in Samba). Some SMB1 write
requests were not correctly range checked to ensure the client had sent
enough data to fulfill the write, allowing server memory contents to be
written into the file (or printer) instead of client supplied data. The
client cannot control the area of the server memory that is written to the
file (or printer) (CVE-2022-3437)
A symlink following vulnerability was found in Samba, where a user can
create a symbolic link that will make 'smbd' escape the configured share
path. This flaw allows a remote user with access to the exported part of
the file system under a share via SMB1 unix extensions or NFS to create
symlinks to files outside the 'smbd' configured share path and gain access
to another restricted server's filesystem. (CVE-2022-3592)
