USN-6013-1: Linux kernel (AWS) vulnerabilities Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment. A remote attacker could use this to cause a denial of service (connection termination) or inject forged data. (CVE-2020-36516) Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk, Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre Variant 2 mitigations for AMD processors on Linux were insufficient in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2021-26401) Jürgen Groß discovered that the Xen subsystem within the Linux kernel did not adequately limit the number of events driver domains (unprivileged PV backends) could send to other guest VMs. An attacker in a driver domain could use this to cause a denial of service [ more… ]

USN-6011-1: Json-smart vulnerabilities It was discovered that Json-smart incorrectly handled memory when processing input containing unclosed quotes. A remote attacker could possibly use this issue to cause applications using Json-smart to crash, leading to a denial of service. (CVE-2021-31684) It was discovered that Json-smart incorrectly handled memory when processing input containing unclosed brackets. A remote attacker could possibly use this issue to cause applications using Json-smart to crash, leading to a denial of service. (CVE-2023-1370) Source: USN-6011-1: Json-smart vulnerabilities

USN-6010-1: Firefox vulnerabilities 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. (CVE-2023-29537, CVE-2023-29540, CVE-2023-29543, CVE-2023-29544, CVE-2023-29547, CVE-2023-29548, CVE-2023-29549, CVE-2023-29550, CVE-2023-29551) Irvan Kurniawan discovered that Firefox did not properly manage fullscreen notifications using a combination of window.open, fullscreen requests, window.name assignments, and setInterval calls. An attacker could potentially exploit this issue to perform spoofing attacks. (CVE-2023-29533) Lukas Bernhard discovered that Firefox did not properly manage memory when doing Garbage Collector compaction. An attacker could potentially exploits this issue to cause a denial of service. (CVE-2023-29535) Zx from qriousec discovered that Firefox did not properly validate the address to free a pointer provided to the memory manager. An attacker could potentially [ more… ]
