CVE-2026-37980 1 Redhat 1 Build Of Keycloak 2026-06-02 N/A 6.9 MEDIUM
A flaw was found in Keycloak, specifically in the organization selection login page. A remote attacker with `manage-realm` or `manage-organizations` administrative privileges can exploit a Stored Cross-Site Scripting (XSS) vulnerability. This flaw occurs because the `organization.alias` is placed into an inline JavaScript `onclick` handler, allowing a crafted JavaScript payload to execute in a user's browser when they view the login page. Successful exploitation enables arbitrary JavaScript execution, potentially leading to session theft, unauthorized account actions, or further attacks against users of the affected realm.
CVE-2026-3832 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-06-02 N/A 3.7 LOW
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
CVE-2026-3833 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-06-02 N/A 6.5 MEDIUM
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-33845 2 Gnu, Redhat 3 Gnutls, Enterprise Linux, Openshift Container Platform 2026-06-02 N/A 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-2023-51767 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2026-06-02 N/A 7.0 HIGH
OpenSSH through 10.0, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. NOTE: this is disputed by the Supplier, who states "we do not consider it to be the application's responsibility to defend against platform architectural weaknesses."
CVE-2025-6170 2 Redhat, Xmlsoft 4 Enterprise Linux, Jboss Core Services, Openshift Container Platform and 1 more 2026-06-02 N/A 2.5 LOW
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
CVE-2025-13601 2 Gnome, Redhat 29 Glib, Ceph Storage, Codeready Linux Builder and 26 more 2026-06-02 N/A 7.7 HIGH
A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.
CVE-2025-26597 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-02 N/A 7.8 HIGH
A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.
CVE-2026-9149 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-06-02 N/A 6.5 MEDIUM
A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).
CVE-2018-3639 12 Arm, Canonical, Debian and 9 more 321 Cortex-a, Ubuntu Linux, Debian Linux and 318 more 2026-05-29 2.1 LOW 5.5 MEDIUM
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.
CVE-2018-13785 4 Canonical, Libpng, Oracle and 1 more 7 Ubuntu Linux, Libpng, Jdk and 4 more 2026-05-29 4.3 MEDIUM 6.5 MEDIUM
In libpng 1.6.34, a wrong calculation of row_factor in the png_check_chunk_length function (pngrutil.c) may trigger an integer overflow and resultant divide-by-zero while processing a crafted PNG file, leading to a denial of service.
CVE-2016-2183 6 Cisco, Nodejs, Openssl and 3 more 9 Content Security Management Appliance, Node.js, Openssl and 6 more 2026-05-29 5.0 MEDIUM 7.5 HIGH
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
CVE-2016-1908 4 Debian, Openbsd, Oracle and 1 more 9 Debian Linux, Openssh, Linux and 6 more 2026-05-29 7.5 HIGH 9.8 CRITICAL
The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server.
CVE-2021-4104 4 Apache, Fedoraproject, Oracle and 1 more 46 Log4j, Fedora, Advanced Supply Chain Planning and 43 more 2026-05-28 6.0 MEDIUM 7.5 HIGH
JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.
CVE-2026-48864 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-05-28 N/A 7.8 HIGH
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
CVE-2019-7317 11 Canonical, Debian, Hp and 8 more 33 Ubuntu Linux, Debian Linux, Xp7 Command View and 30 more 2026-05-28 2.6 LOW 5.3 MEDIUM
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.
CVE-2019-6109 9 Canonical, Debian, Fedoraproject and 6 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2026-05-28 4.0 MEDIUM 6.8 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.
CVE-2019-11135 9 Canonical, Debian, Fedoraproject and 6 more 304 Ubuntu Linux, Debian Linux, Fedora and 301 more 2026-05-28 2.1 LOW 6.5 MEDIUM
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.
CVE-2017-15906 5 Debian, Netapp, Openbsd and 2 more 22 Debian Linux, Active Iq Unified Manager, Cloud Backup and 19 more 2026-05-28 5.0 MEDIUM 5.3 MEDIUM
The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files.
CVE-2014-3566 11 Apple, Debian, Fedoraproject and 8 more 20 Mac Os X, Debian Linux, Fedora and 17 more 2026-05-28 4.3 MEDIUM 3.4 LOW
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.
