Red Hat Security Advisory 2023-3723-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include null pointer, out of bounds access, out of bounds write, privilege escalation, and use-after-free vulnerabilities.

Red Hat Security Advisory 2023-3708-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include null pointer, out of bounds access, out of bounds write, privilege escalation, and use-after-free vulnerabilities.

Red Hat Security Advisory 2023-3722-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength general-purpose cryptography library. Issues addressed include buffer over-read and denial of service vulnerabilities.

Why Data Exfiltration Detection is Paramount? The world is witnessing an exponential rise in ransomware and data theft employed to extort companies. At the same time, the industry faces numerous critical vulnerabilities in database software and company websites. This evolution paints a dire picture of data exposure and exfiltration that every security leader and team is grappling with. This

Newly released documents highlight the bureau's continued secrecy around cell-site simulators—spying tech that everyone already assumes exists.

Dell PowerStore versions prior to 3.5 contain an improper verification of cryptographic signature vulnerability. An attacker can trick a high privileged user to install a malicious binary by bypassing the existing cryptographic signature checks

IBM SPSS Modeler on Windows 17.0, 18.0, 18.2.2, 18.3, 18.4, and 18.5 requires the end user to have access to the server SSL key which could allow a local user to decrypt and obtain sensitive information. IBM X-Force ID: 256117.

This article is the last in a six-part series (see my previous blog) presenting various usage models for Confidential Computing, a set of technologies designed to protect data in use. In this article, I explore interesting support technologies under active development in the confidential computing community. Kernel, hypervisor and firmware support Confidential Computing requires support from the host and guest kernel, the hypervisor, and firmware. At the time of writing, that support is uneven between platforms. Hardware vendors tend to develop and submit relatively large patch series, w

When this function was passed an empty string, `openssl` would attempt to call `strlen` on it, reading arbitrary memory until it reached a NUL byte.

Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the `max-cache-size` statement in the configuration file; it defaults to 90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets from the cache, to keep memory use below the configured limit. It has been discovered that the effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0 through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9...
