If CEOs want to prevent their firm from being the next victim of a high-profile deepfake scam, they need to double cybersecurity funding immediately.

Ubuntu Security Notice 6747-2 - USN-6747-1 fixed vulnerabilities in Firefox. The update introduced several minor regressions. This update fixes the problem. Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Bartek Nowotarski discovered that Firefox did not properly limit HTTP/2 CONTINUATION frames. An attacker could potentially exploit this issue to cause a denial of service. Gary Kwong discovered that Firefox did not properly manage memory when running garbage collection during realm initialization. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. Lukas Bernhard discovered that Firefox did not properly manage memory during JIT optimizations, leading to an out-of-bounds read vulnerability. An attacker could possibly use...

The newly discovered malware, which has so far mainly targeted Turkish telcos and has links to HiatusRat, infects routers and performs DNS and HTTP hijacking attacks on connections to private IP addresses.

### Summary Default configuration does not check authorization of the signer, it only checks the validity of the signature per section 3.2.2 of https://www.w3.org/TR/2008/REC-xmldsig-core-20080610/#sec-CoreValidation. As such, without additional validation steps, the default configuration allows a malicious actor to re-sign an XML document, place the certificate in a `<KeyInfo />` element, and pass `xml-crypto` default validation checks. ### Details Affected `xml-crypto` versions between versions `>= 4.0.0` and `< 6.0.0`. `xml-crypto` trusts by default any certificate provided via digitally signed XML document's `<KeyInfo />`. `xml-crypto` prefers to use any certificate provided via digitally signed XML document's `<KeyInfo />` even if library was configured to use specific certificate (`publicCert`) for signature verification purposes. Attacker can spoof signature verification by modifying XML document and replacing existing signature with signature generated with malicious pri...

Ubuntu Security Notice 6760-1 - George-Andrei Iosif and David Fernandez Gonzalez discovered that Gerbv did not properly initialize a data structure when parsing certain nested RS-274X format files. If a user were tricked into opening a specially crafted file, an attacker could possibly use this issue to cause a denial of service.

Lonial Con discovered that the netfilter subsystem in the Linux kernel contained a memory leak when handling certain element flush operations. A local attacker could use this to expose sensitive information (kernel memory). Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle inactive elements in its PIPAPO data structure, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.

Ubuntu Security Notice 6761-1 - It was discovered that Anope did not properly process credentials for suspended accounts. An attacker could possibly use this issue to normally login to the platform as a suspended user after changing their password.

March 29, 2024 is a day that will hardly be forgotten by the open source community: Andres Freund disclosed his findings about the compromise in the xz compression library, which would enable an attacker to silently gain access to a targeted affected system. How did that coordination work under the hood? In this article we will give a behind the scenes glimpse into what this looked like at Red Hat.DiscoveryOn Wednesday, March 27, Andres contacted the Debian security team via their contact email ([email protected]) and let them know about the oddities he found in a SSH slowdown when using a n

Tracking code used for keeping tabs on how members navigated through the healthcare giant's online and mobile sites was oversharing a concerning amount of information.

Ubuntu Security Notice 6744-3 - USN-6744-1 fixed a vulnerability in Pillow. This update provides the corresponding updates for Ubuntu 24.04 LTS. Hugo van Kemenade discovered that Pillow was not properly performing bounds checks when processing an ICC file, which could lead to a buffer overflow. If a user or automated system were tricked into processing a specially crafted ICC file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code.
