| CVE-2026-42010 | 2 Gnu, Redhat | 15 Gnutls, Ai Inference Server, Discovery and 12 more | 2026-08-31 | 7.1 High |
| A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process. | ||||
| CVE-2026-42009 | 2 Gnu, Redhat | 26 Gnutls, Ai Inference Server, Discovery and 23 more | 2026-08-31 | 7.5 High |
| A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service. | ||||
| CVE-2026-33846 | 2 Gnu, Redhat | 16 Gnutls, Ai Inference Server, Discovery and 13 more | 2026-08-31 | 7.5 High |
| A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption. | ||||
| CVE-2026-33845 | 2 Gnu, Redhat | 16 Gnutls, Ai Inference Server, Discovery and 13 more | 2026-08-31 | 7.5 High |
| A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service. | ||||
| CVE-2025-8419 | 1 Redhat | 2 Build Keycloak, Keycloak | 2026-08-31 | 5.3 Medium |
| A vulnerability was found in Keycloak-services. Special characters used during e-mail registration may perform SMTP Injection and unexpectedly send short unwanted e-mails. The email is limited to 64 characters (limited local part of the email), so the attack is limited to very shorts emails (subject and little data, the example is 60 chars). This flaw's only direct consequence is an unsolicited email being sent from the Keycloak server. However, this action could be a precursor for more sophisticated attacks. | ||||
| CVE-2024-11736 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp | 2026-08-31 | 4.9 Medium |
| A vulnerability was found in Keycloak. Admin users may have to access sensitive server environment variables and system properties through user-configurable URLs. When configuring backchannel logout URLs or admin URLs, admin users can include placeholders like ${env.VARNAME} or ${PROPNAME}. The server replaces these placeholders with the actual values of environment variables or system properties during URL processing. | ||||
| CVE-2024-11734 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp | 2026-08-31 | 6.5 Medium |
| A denial of service vulnerability was found in Keycloak that could allow an administrative user with the right to change realm settings to disrupt the service. This action is done by modifying any of the security headers and inserting newlines, which causes the Keycloak server to write to a request that has already been terminated, leading to the failure of said request. | ||||
| CVE-2024-9666 | 1 Redhat | 2 Build Keycloak, Jboss Enterprise Application Platform | 2026-08-31 | 4.7 Medium |
| A vulnerability was found in the Keycloak Server. The Keycloak Server is vulnerable to a denial of service (DoS) attack due to improper handling of proxy headers. When Keycloak is configured to accept incoming proxy headers, it may accept non-IP values, such as obfuscated identifiers, without proper validation. This issue can lead to costly DNS resolution operations, which an attacker could exploit to tie up IO threads and potentially cause a denial of service. The attacker must have access to send requests to a Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not overwrite incoming headers, and Keycloak is configured to trust these headers. | ||||
| CVE-2026-64194 | 1 Nlnet Labs | 1 Net Dns | 2026-08-30 | 7.5 High |
| Net::DNS versions through 1.55 for Perl allow Denial of Service via deep DNS compression pointer chains. Net::DNS::DomainName::decode follows RFC 1035 compression pointers by recursing into itself with no depth limit. It is possible to construct a name which saturates the call stack (at least with larger TCP responses), leading to a potential Denial of Service. The guard `$link < $offset` prevents forward and circular chains, but still allows arbitrarily long backward chains. The per-offset cache (`$cache`) is populated at the start of each call and short-circuits only re-traverses of the same offset - the initial descent through a fresh chain still recurses at full depth. A crafted packet can chain two-byte compression pointers so that each one points two bytes earlier than the previous, producing a chain length of `offset / 2`. For the 14-bit pointer field (max offset 16383) this gives up to ~8191 recursive frames. For a TCP DNS message the limit is the 16-bit length field (~32767 frames). Perl's default C stack handles only a few thousand frames; beyond that the process receives SIGSEGV or similar, which is a denial-of-service for any application parsing untrusted DNS data. The vulnerability is triggered by `Net::DNS::Packet->new(\$wire)` i.e. any point where the library decodes a DNS message from the network. | ||||

| CVE-2026-82547 | 2 Linux Foundation, Linuxfoundation | 2 Magma, Magma | 2026-08-30 | 6.5 Medium |
| A vulnerability was found in Linux Foundation Magma 1.9.0. The affected element is an unknown function of the file tasks/amf/amf_fsm.cpp of the component Registration Complete Message Handler.

| CVE-2026-82658 | 1 Admidio | 1 Admidio | 2026-08-30 | 4.3 Medium |
| Admidio versions before 5.0.12 contain a broken access control vulnerability in profile_function.php that allows authenticated low-privilege users to read another user's future role memberships. Attackers can bypass profile-level authorization by directly calling the reload_future_memberships endpoint with a victim's user UUID to disclose sensitive membership information. | ||||
