CVE-2023-42669 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 7 more 2025-11-20 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.
CVE-2023-4527 4 Fedoraproject, Gnu, Netapp and 1 more 32 Fedora, Glibc, H300s and 29 more 2025-11-20 6.5 Medium
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
CVE-2023-4091 3 Fedoraproject, Redhat, Samba 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more 2025-11-20 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-2024-1062 2 Fedoraproject, Redhat 16 Fedora, 389 Directory Server, Directory Server and 13 more 2025-11-20 5.5 Medium
A heap overflow flaw was found in 389-ds-base. This issue leads to a denial of service when writing a value larger than 256 chars in log_entry_attr.
CVE-2023-5455 3 Fedoraproject, Freeipa, Redhat 25 Fedora, Freeipa, Codeready Linux Builder and 22 more 2025-11-20 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-2023-47038 3 Fedoraproject, Perl, Redhat 5 Fedora, Perl, Enterprise Linux and 2 more 2025-11-20 7 High
A vulnerability was found in perl 5.30.0 through 5.38.0. This issue occurs when a crafted regular expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer.
CVE-2023-4806 3 Fedoraproject, Gnu, Redhat 24 Fedora, Glibc, Codeready Linux Builder Eus and 21 more 2025-11-20 5.9 Medium
A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.
CVE-2023-38201 3 Fedoraproject, Keylime, Redhat 9 Fedora, Keylime, Enterprise Linux and 6 more 2025-11-20 6.5 Medium
A flaw was found in the Keylime registrar that could allow a bypass of the challenge-response protocol during agent registration. This issue may allow an attacker to impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database.
CVE-2023-38200 3 Fedoraproject, Keylime, Redhat 9 Fedora, Keylime, Enterprise Linux and 6 more 2025-11-20 7.5 High
A flaw was found in Keylime. Due to their blocking nature, the Keylime registrar is subject to a remote denial of service against its SSL connections. This flaw allows an attacker to exhaust all available connections.
CVE-2025-59088 1 Redhat 7 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 4 more 2025-11-20 8.6 High
If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request for a realm matching a DNS zone where they created SRV records pointing to arbitrary ports and hostnames (which may resolve to loopback or internal IP addresses). This vulnerability can be exploited to probe internal network topology and firewall rules, perform port scanning, and exfiltrate data. Deployments where the "use_dns" setting is explicitly set to false are not affected.
CVE-2023-3972 1 Redhat 23 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Desktop and 20 more 2025-11-20 7.8 High
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).
CVE-2023-3899 2 Fedoraproject, Redhat 24 Fedora, Enterprise Linux, Enterprise Linux Desktop and 21 more 2025-11-20 7.8 High
A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root.
CVE-2024-3183 1 Redhat 9 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Eus and 6 more 2025-11-20 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-2024-2698 2 Freeipa, Redhat 4 Freeipa, Enterprise Linux, Enterprise Linux Eus and 1 more 2025-11-20 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-2023-4147 4 Debian, Fedoraproject, Linux and 1 more 9 Debian Linux, Fedora, Linux Kernel and 6 more 2025-11-20 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-2023-6478 4 Debian, Redhat, Tigervnc and 1 more 11 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 8 more 2025-11-20 7.6 High
A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information.
CVE-2023-6377 4 Debian, Redhat, Tigervnc and 1 more 11 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 8 more 2025-11-20 7.8 High
A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.
CVE-2023-46848 2 Redhat, Squid-cache 6 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 3 more 2025-11-20 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 15 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 12 more 2025-11-20 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-2023-46846 2 Redhat, Squid-cache 13 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 10 more 2025-11-20 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.
