USN-4978-1: 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, re-enable camera devices without an additional permission prompt, spoof the browser UI, or execute arbitrary code. (CVE-2021-29959, CVE-2021-29961, CVE-2021-29966, CVE-2021-29967) It was discovered that filenames printed from private browsing mode were incorrectly retained in preferences. A local attacker could potentially exploit this to obtain sensitive information. (CVE-2021-29960) Source: USN-4978-1: Firefox vulnerabilities

USN-4977-1: Linux kernel vulnerabilities Kiyin (尹亮) discovered that the NFC LLCP protocol implementation in the Linux kernel contained a reference counting error. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-25670) Kiyin (尹亮) discovered that the NFC LLCP protocol implementation in the Linux kernel did not properly deallocate memory in certain error situations. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2020-25671, CVE-2020-25672) Kiyin (尹亮) discovered that the NFC LLCP protocol implementation in the Linux kernel did not properly handle error conditions in some situations, leading to an infinite loop. A local attacker could use this to cause a denial of service. (CVE-2020-25673) Piotr Krysiuk and Benedict Schlueter discovered that the eBPF implementation in the Linux kernel performed out of bounds speculation on pointer arithmetic. A local attacker [ more… ]
