30 Jun 2023 — A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. ... • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-400: Uncontrolled Resource Consumption •

28 Jun 2023 — Keycloak's device authorization grant does not correctly validate the device code and client ID. An attacker client could abuse the missing validation to spoof a client consent request and trick an authorization admin into granting consent to a malicious OAuth client or possible unauthorized access to an existing OAuth client.

28 Jun 2023 — A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients. Se encontró una falla en Keycloak.

23 Jun 2023 — A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL.

22 Jun 2023 — A flaw was found in the Libreoffice package. An attacker can craft an odb containing a "database/script" file with a SCRIPT command where the contents of the file could be written to a new file whose location was determined by the attacker. Gregor Kopf of Secfault Security GmbH discovered that HSQLDB, a Java SQL database engine, allowed the execution of spurious scripting commands in .script and .log files. Hsqldb supports a "SCRIPT" keyword which is normally used to record the commands input by the databas... • http://www.openwall.com/lists/oss-security/2023/12/28/4 • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

16 Jun 2023 — A vulnerability was found in libX11. The security flaw occurs because the functions in src/InitExt.c in libX11 do not check that the values provided for the Request, Event, or Error IDs are within the bounds of the arrays that those functions write to, using those IDs as array indexes. They trust that they were called with values provided by an Xserver adhering to the bounds specified in the X11 protocol, as all X servers provided by X.Org do. As the protocol only specifies a single byte for these values, a... • https://access.redhat.com/security/cve/CVE-2023-3138 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
