GitLab has released security updates to address two critical vulnerabilities, including one that could be exploited to take over accounts without requiring any user interaction. Tracked as CVE-2023-7028, the flaw has been awarded the maximum severity of 10.0 on the CVSS scoring system and could facilitate account takeover by sending password reset emails to an unverified email address. The

Picture a cybersecurity landscape where defenses are impenetrable, and threats are nothing more than mere disturbances deflected by a strong shield. Sadly, this image of fortitude remains a pipe dream despite its comforting nature. In the security world, preparedness is not just a luxury but a necessity. In this context, Mike Tyson's famous adage, "Everyone has a plan until they get punched in

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical security vulnerability impacting Microsoft SharePoint Server to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The issue, tracked as CVE-2023-29357 (CVSS score: 9.8), is a privilege escalation flaw that could be exploited by an attacker to gain

Ubuntu Security Notice 6578-1 - Vishal Mishra and Anita Gaud discovered that .NET did not properly validate X.509 certificates with malformed signatures. An attacker could possibly use this issue to bypass an application's typical authentication logic. Morgan Brown discovered that .NET did not properly handle requests from unauthenticated clients. An attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 6560-2 - USN-6560-1 fixed several vulnerabilities in OpenSSH. This update provides the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Fabian Bäumer, Marcus Brinkmann, Joerg Schwenk discovered that the SSH protocol was vulnerable to a prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension negotiation messages could be truncated, possibly leading to certain algorithms and features being downgraded. This issue is known as the Terrapin attack. This update adds protocol extensions to mitigate this issue.

Ubuntu Security Notice 6579-1 - It was discovered that Xerces-C++ was not properly handling memory management operations when parsing XML data containing external DTDs, which could trigger a use-after-free error. If a user or automated system were tricked into processing a specially crafted XML document, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

WordPress POST SMTP Mailer plugin versions 2.8.7 and below suffer from authorization bypass and cross site scripting vulnerabilities.

Ubuntu Security Notice 6574-1 - Takeshi Kaneko discovered that Go did not properly handle comments and special tags in the script context of html/template module. An attacker could possibly use this issue to inject Javascript code and perform a cross site scripting attack. This issue only affected Go 1.20 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 23.04. It was discovered that Go did not properly validate the "//go:cgo_" directives during compilation. An attacker could possibly use this issue to inject arbitrary code during compile time.

Ubuntu Security Notice 6562-2 - USN-6562-1 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. DoHyun Lee discovered that Firefox did not properly manage memory when used on systems with the Mesa VM driver. An attacker could potentially exploit this issue to execute arbitrary code. George Pantela and Hubert Kario discovered that Firefox using multiple NSS NIST curves which were susceptible to a side-channel attack known as "Minerva". An attacker could potentially exploit this issue to obtain sensitive information. Andrew Osmond discovered that Firefox did not properly validate the textures produced by remote decoders. An attacker could potentially exploit this issue...

Ubuntu Security Notice 6577-1 - Jana Hofmann, Emanuele Vannacci, Cedric Fournet, Boris Kopf, and Oleksii Oleksenko discovered that some AMD processors could leak stale data from division operations in certain situations. A local attacker could possibly use this to expose sensitive information. It was discovered that a race condition existed in the Linux kernel when performing operations with kernel objects, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service or execute arbitrary code.
