Samba is an open-source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information.

The following packages have been upgraded to a later upstream version: samba (4.18.6). (BZ#2190415)

Security Fix(es):

* samba: out-of-bounds read in winbind AUTH_CRAP (CVE-2022-2127) * samba: infinite loop in mdssvc RPC service for spotlight (CVE-2023-34966) * samba: type confusion in mdssvc RPC service for spotlight (CVE-2023-34967) * samba: spotlight server-side share path disclosure (CVE-2023-34968)

An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can trigger an out-of-bounds read in Winbind, possibly resulting in a crash.

OESA-2023-1449 — samba security update

Affected: openEuler:20.03-LTS-SP1: samba

Samba is a suite of programs for Linux and Unix to interoperate with Windows.

Security Fix(es):

An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not validate a field in the network packet that contains the count of elements in an array-like structure. By passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This flaw allows an attacker to issue a malformed RPC request, triggering an infinite loop, resulting in a denial of service condition.(CVE-2023-34966)

A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a lack of type checking in caller…
