https://notcve.org/view.php?id=CVE-2023-3772
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. • http://www.openwall.com/lists/oss-security/2023/08/10/1 http://www.openwall.com/lists/oss-security/2023/08/10/3 https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/errata/RHSA-2023:6901 https://access.redhat.com/errata/RHSA-2023:7077 https://access.redhat.com/errata/RHSA-2024:0412 https://access.redhat.com/errata/RHSA-2024:0575 https://access.redhat.com/security/cve/CVE-2023-3772 https://bugzilla.redhat.com/show_bug.cgi?id=2218943 https&# • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2023-34968
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. • https://access.redhat.com/errata/RHSA-2023:6667 https://access.redhat.com/errata/RHSA-2023:7139 https://access.redhat.com/errata/RHSA-2024:0423 https://access.redhat.com/errata/RHSA-2024:0580 https://access.redhat.com/security/cve/CVE-2023-34968 https://bugzilla.redhat.com/show_bug.cgi?id=2222795 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPCSGND7LO467AJGR5DYBGZLTCGTOBCC https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject. •
CVSS: 5.9EPSS: 21%CPEs: 9EXPL: 0CVE-2023-34967 – Samba: type confusion in mdssvc rpc service for spotlight
https://notcve.org/view.php?id=CVE-2023-34967
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 callers of the dalloc_value_for_key() function, which returns the object associated with a key, a caller may trigger a crash in talloc_get_size() when talloc detects that the passed-in pointer is not a valid talloc pointer. With an RPC worker process shared among multiple client connections, a malicious client or attacker can trigger a process crash in a shared RPC mdssvc worker process, affecting all other clients this worker serves. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Samba. • https://access.redhat.com/errata/RHSA-2023:6667 https://access.redhat.com/errata/RHSA-2023:7139 https://access.redhat.com/errata/RHSA-2024:0423 https://access.redhat.com/errata/RHSA-2024:0580 https://access.redhat.com/security/cve/CVE-2023-34967 https://bugzilla.redhat.com/show_bug.cgi?id=2222794 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPCSGND7LO467AJGR5DYBGZLTCGTOBCC https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject. • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVSS: 7.5EPSS: 11%CPEs: 9EXPL: 0CVE-2023-34966 – Samba: infinite loop in mdssvc rpc service for spotlight
https://notcve.org/view.php?id=CVE-2023-34966
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. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Samba. • https://access.redhat.com/errata/RHSA-2023:6667 https://access.redhat.com/errata/RHSA-2023:7139 https://access.redhat.com/errata/RHSA-2024:0423 https://access.redhat.com/errata/RHSA-2024:0580 https://access.redhat.com/errata/RHSA-2024:4101 https://access.redhat.com/security/cve/CVE-2023-34966 https://bugzilla.redhat.com/show_bug.cgi?id=2222793 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPCSGND7LO467AJGR5DYBGZLTCGTOBCC https://lists.fedoraproje • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2022-2127
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. • https://access.redhat.com/errata/RHSA-2023:6667 https://access.redhat.com/errata/RHSA-2023:7139 https://access.redhat.com/errata/RHSA-2024:0423 https://access.redhat.com/errata/RHSA-2024:0580 https://access.redhat.com/security/cve/CVE-2022-2127 https://bugzilla.redhat.com/show_bug.cgi?id=2222791 https://lists.debian.org/debian-lts-announce/2024/04/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPCSGND7LO467AJGR5DYBGZLTCGTOBCC https:& • CWE-125: Out-of-bounds Read •
