samba: fix CVE-2018-14628

2024-02-07T23:41:41+00:00

samba: fix CVE-2023-42669

2024-01-12T12:14:16+00:00

A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task. References: https://nvd.nist.gov/vuln/detail/CVE-2023-42669 Signed-off-by: Archana Polampalli Signed-off-by: Armin Kuster

samba: fix CVE-2023-4091

2023-12-13T18:35:51+00:00

A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "acl_xattr" is configured with "acl_xattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create disposition request. The issue arises in configurations that bypass kernel file system permissions checks, relying solely on Samba's permissions. References: https://nvd.nist.gov/vuln/detail/CVE-2023-4091 Fix is patched to the function call smbd_check_access_rights_fsp() of open_file(), But in samba_4.14.14 smbd_check_access_rights() is used, from samba_4.15.0 onwards smbd_check_access_rights() was replaced with smbd_check_access_rights_fsp() and samba_4.14.14 is still vulnerable through smbd_check_access_rights().

samba: fix CVE-2023-34968

2023-10-17T12:42:14+00:00

A path disclosure vulnerability was found in Samba. As part of the Spotlight protocol, Samba discloses the server-side absolute path of shares, files, and directories in the results for search queries. This flaw allows a malicious client or an attacker with a targeted RPC request to view the information that is part of the disclosed path.

samba: fix CVE-2021-44758

2023-06-17T18:22:30+00:00

Heimdal before 7.7.1 allows attackers to cause a NULL pointer dereference in a SPNEGO acceptor via a preferred_mech_type of GSS_C_NO_OID and a nonzero initial_response value to send_accept.

samba: fix CVE-2022-41916

2023-06-17T18:22:25+00:00

Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos. Versions prior to 7.7.1 are vulnerable to a denial of service vulnerability in Heimdal's PKI certificate validation library, affecting the KDC (via PKINIT) and kinit (via PKINIT), as well as any third-party applications using Heimdal's libhx509. Users should upgrade to Heimdal 7.7.1 or 7.8. There are no known workarounds for this issue.
