CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2023-4004 – Kernel: netfilter: use-after-free due to improper element removal in nft_pipapo_remove()
https://notcve.org/view.php?id=CVE-2023-4004
A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system. Se encontró una falla de use-after-free en el netfilter del kernel de Linux en la forma en que un usuario activa la función nft_pipapo_remove con el elemento, sin un NFT_SET_EXT_KEY_END. Este problema podría permitir que un usuario local bloquee el sistema o potencialmente aumente sus privilegios en el sistema. • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://access.redhat.com/errata/RHSA-2023:4961 https://access.redhat.com/errata/RHSA-2023:4962 https://access.redhat.com/errata/RHSA-2023:4967 https://access.redhat.com/errata/RHSA-2023:5069 https://access.redhat.com/errata/RHSA-2023:5091 https://access.redhat.com/errata/RHSA-2023:5093 https:// • CWE-416: Use After Free •

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 cause a 4 byte out-of-bounds read of XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data to userspace. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/security/cve/CVE-2023-3773 https://bugzilla.redhat.com/show_bug.cgi?id=2218944 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://www.debian.org/security/2023/dsa-5492 • CWE-125: Out-of-bounds Read •

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: 29%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') •
