CVE-2022-24806 4 Debian, Fedoraproject, Net-snmp and 1 more 15 Debian Linux, Fedora, Net-snmp and 12 more 2025-01-17 N/A 6.5 MEDIUM
net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a user with read-write credentials can exploit an Improper Input Validation vulnerability when SETing malformed OIDs in master agent and subagent simultaneously. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. Those who must use SNMPv1 or SNMPv2c should use a complex community string and enhance the protection by restricting access to a given IP address range.
CVE-2022-24805 4 Debian, Fedoraproject, Net-snmp and 1 more 15 Debian Linux, Fedora, Net-snmp and 12 more 2025-01-17 N/A 6.5 MEDIUM
net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a buffer overflow in the handling of the `INDEX` of `NET-SNMP-VACM-MIB` can cause an out-of-bounds memory access. A user with read-only credentials can exploit the issue. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. Those who must use SNMPv1 or SNMPv2c should use a complex community string and enhance the protection by restricting access to a given IP address range.
CVE-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2025-01-14 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
CVE-2017-18017 9 Arista, Canonical, Debian and 6 more 29 Eos, Ubuntu Linux, Debian Linux and 26 more 2025-01-03 10.0 HIGH 9.8 CRITICAL
The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.
CVE-2018-12121 2 Nodejs, Redhat 8 Node.js, Enterprise Linux, Enterprise Linux Desktop and 5 more 2024-12-27 5.0 MEDIUM 7.5 HIGH
Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.
CVE-2023-46846 2 Redhat, Squid-cache 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 5 more 2024-12-18 N/A 9.3 CRITICAL
SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote attacker to perform Request/Response smuggling past firewall and frontend security systems.
CVE-2024-2698 2 Freeipa, Redhat 3 Freeipa, Enterprise Linux, Enterprise Linux Eus 2024-11-24 N/A 8.8 HIGH
A vulnerability was found in FreeIPA in how the initial implementation of MS-SFU by MIT Kerberos was missing a condition for granting the "forwardable" flag on S4U2Self tickets. Fixing this mistake required adding a special case for the check_allowed_to_delegate() function: If the target service argument is NULL, then it means the KDC is probing for general constrained delegation rules and not checking a specific S4U2Proxy request. In FreeIPA 4.11.0, the behavior of ipadb_match_acl() was modified to match the changes from upstream MIT Kerberos 1.20. However, a mistake resulting in this mechanism applies in cases where the target service argument is set AND where it is unset. This results in S4U2Proxy requests being accepted regardless of whether or not there is a matching service delegation rule.
CVE-2024-3183 1 Redhat 5 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Eus and 2 more 2024-11-21 N/A 8.1 HIGH
A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client’s session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the user’s password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principal’s password).
CVE-2023-6606 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 2 more 2024-11-21 N/A 7.1 HIGH
An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.

CVE-2023-6356 3 Debian, Linux, Redhat 17 Debian Linux, Linux Kernel, Codeready Linux Builder Eus and 14 more 2024-11-21 N/A 6.5 MEDIUM
A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service.
CVE-2023-5992 2 Opensc Project, Redhat 11 Opensc, Enterprise Linux, Enterprise Linux Eus and 8 more 2024-11-21 N/A 5.6 MEDIUM
A vulnerability was found in OpenSC where PKCS#1 encryption padding removal is not implemented as side-channel resistant. This issue may result in the potential leak of private data.
CVE-2023-5633 2 Linux, Redhat 22 Linux Kernel, Codeready Linux Builder, Codeready Linux Builder Eus and 19 more 2024-11-21 N/A 7.8 HIGH
The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory objects were handled when they were being used to store a surface. When running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially use this flaw to escalate their privileges.
CVE-2023-5455 3 Fedoraproject, Freeipa, Redhat 21 Fedora, Freeipa, Codeready Linux Builder and 18 more 2024-11-21 N/A 6.5 MEDIUM
A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing already logged-in user. An attacker would always have to go through a new authentication attempt.
CVE-2023-4147 4 Debian, Fedoraproject, Linux and 1 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2024-11-21 N/A 7.8 HIGH
A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
CVE-2023-4091 3 Fedoraproject, Redhat, Samba 5 Fedora, Enterprise Linux, Enterprise Linux Eus and 2 more 2024-11-21 N/A 6.5 MEDIUM
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.
CVE-2023-46848 2 Redhat, Squid-cache 5 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 2 more 2024-11-21 N/A 8.6 HIGH
Squid is vulnerable to Denial of Service, where a remote attacker can perform DoS by sending ftp:// URLs in HTTP Request messages or constructing ftp:// URLs from FTP Native input.
CVE-2023-46847 2 Redhat, Squid-cache 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 7 more 2024-11-21 N/A 8.6 HIGH
Squid is vulnerable to a Denial of Service, where a remote attacker can perform buffer overflow attack by writing up to 2 MB of arbitrary data to heap memory when Squid is configured to accept HTTP Digest Authentication.
CVE-2023-42669 2 Redhat, Samba 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 5 more 2024-11-21 N/A 6.5 MEDIUM
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.
