CVE-2024-1062 2 Fedoraproject, Redhat 13 Fedora, 389 Directory Server, Directory Server and 10 more 2026-06-17 N/A 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-2024-0409 4 Fedoraproject, Redhat, Tigervnc and 1 more 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more 2026-06-17 N/A 7.8 HIGH
A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context.
CVE-2024-0408 4 Fedoraproject, Redhat, Tigervnc and 1 more 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more 2026-06-17 N/A 5.5 MEDIUM
A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.
CVE-2024-0193 2 Linux, Redhat 23 Linux Kernel, Codeready Linux Builder, Codeready Linux Builder For Eus and 20 more 2026-06-17 N/A 7.8 HIGH
A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with CAP_NET_ADMIN capability to escalate their privileges on the system.
CVE-2023-7250 2 Es, Redhat 5 Iperf3, Enterprise Linux, Enterprise Linux For Arm 64 and 2 more 2026-06-17 N/A 5.3 MEDIUM
A flaw was found in iperf, a utility for testing network performance using TCP, UDP, and SCTP. A malicious or malfunctioning client can send less than the expected amount of data to the iperf server, which can cause the server to hang indefinitely waiting for the remainder or until the connection gets closed. This will prevent other connections to the server, leading to a denial of service.
CVE-2023-6681 3 Fedoraproject, Latchset, Redhat 6 Fedora, Jwcrypto, Enterprise Linux and 3 more 2026-06-17 N/A 5.3 MEDIUM
A vulnerability was found in JWCrypto. This flaw allows an attacker to cause a denial of service (DoS) attack and possible password brute-force and dictionary attacks to be more resource-intensive. This issue can result in a large amount of computational consumption, causing a denial of service attack.
CVE-2023-5992 2 Opensc Project, Redhat 11 Opensc, Enterprise Linux, Enterprise Linux Eus and 8 more 2026-06-17 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-2023-5870 2 Postgresql, Redhat 16 Postgresql, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 13 more 2026-06-17 N/A 2.2 LOW
A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
CVE-2023-5869 2 Postgresql, Redhat 21 Postgresql, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 18 more 2026-06-17 N/A 8.8 HIGH
A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory.
CVE-2023-5633 2 Linux, Redhat 22 Linux Kernel, Codeready Linux Builder, Codeready Linux Builder Eus and 19 more 2026-06-17 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 2026-06-17 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-2023-5157 3 Fedoraproject, Mariadb, Redhat 12 Fedora, Mariadb, Enterprise Linux and 9 more 2026-06-17 N/A 7.5 HIGH
A vulnerability was found in MariaDB. An OpenVAS port scan on ports 3306 and 4567 allows a malicious remote client to cause a denial of service.
CVE-2023-4911 7 Canonical, Debian, Fedoraproject and 4 more 49 Ubuntu Linux, Debian Linux, Fedora and 46 more 2026-06-17 N/A 7.8 HIGH
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2023-4732 2 Linux, Redhat 10 Linux Kernel, Codeready Linux Builder, Codeready Linux Builder For Arm64 and 7 more 2026-06-17 N/A 4.7 MEDIUM
A flaw was found in pfn_swap_entry_to_page in memory management subsystem in the Linux Kernel. In this flaw, an attacker with a local user privilege may cause a denial of service problem due to a BUG statement referencing pmd_t x.
CVE-2023-4641 2 Redhat, Shadow-maint 9 Codeready Linux Builder, Codeready Linux Builder For Arm64, Codeready Linux Builder For Ibm Z Systems and 6 more 2026-06-17 N/A 4.7 MEDIUM
A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.
CVE-2023-4527 4 Fedoraproject, Gnu, Netapp and 1 more 32 Fedora, Glibc, H300s and 29 more 2026-06-17 N/A 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-2023-4042 2 Artifex, Redhat 9 Ghostscript, Codeready Linux Builder, Codeready Linux Builder For Arm64 and 6 more 2026-06-17 N/A 5.5 MEDIUM
A flaw was found in ghostscript. The fix for CVE-2020-16305 in ghostscript was not included in RHSA-2021:1852-06 advisory as it was claimed to be. This issue only affects the ghostscript package as shipped with Red Hat Enterprise Linux 8.
CVE-2023-46847 2 Redhat, Squid-cache 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 7 more 2026-06-17 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-2023-46846 2 Redhat, Squid-cache 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 5 more 2026-06-17 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-2023-42669 2 Redhat, Samba 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 5 more 2026-06-17 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.
