CVE-2021-44142
Orange Tsai reported an out-of-bounds heap write vulnerability in the VFS module vfs_fruit, which could result in remote execution of arbitrary code as root.
CVE-2022-0336
Kees van Vloten reported that Samba AD users with permission to write to an account can impersonate arbitrary services.
For the oldstable distribution (buster), these problems have been fixed in version 2:4.9.5+dfsg-5+deb10u3. As per DSA 5015-1, CVE-2022-0336 has not been addressed for the oldstable distribution (buster).
For the stable distribution (bullseye), these problems have been fixed in version 2:4.13.13+dfsg-1~deb11u3. Additionally, some followup fixes for CVE-2020-25717 are included in this update (Cf. #1001068).
We recommend that you upgrade your samba packages.
For the detailed security status of samba please refer to its security tracker page at: [link moved to references]");
