USN-4679-1: Linux kernel vulnerabilities It was discovered that the console keyboard driver in the Linux kernel contained a race condition. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2020-25656) Minh Yuan discovered that the tty driver in the Linux kernel contained race conditions when handling fonts. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2020-25668) Kiyin (尹亮) discovered that the perf subsystem in the Linux kernel did not properly deallocate memory in some situations. A privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2020-25704) Jinoh Kang discovered that the Xen event channel infrastructure in the Linux kernel contained a race condition. An attacker in guest could possibly use this to cause a denial of service (dom0 crash). (CVE-2020-27675) Daniel Axtens discovered that PowerPC RTAS implementation [ more… ]

USN-4677-1: p11-kit vulnerabilities David Cook discovered that p11-kit incorrectly handled certain memory operations. An attacker could use this issue to cause p11-kit to crash, resulting in a denial of service, or possibly execute arbitrary code. Source: USN-4677-1: p11-kit vulnerabilities

USN-4676-1: OpenEXR vulnerabilities It was discovered that OpenEXR incorrectly handled certain malformed EXR image files. If a user were tricked into opening a crafted EXR image file, a remote attacker could cause a denial of service, or possibly execute arbitrary code. Source: USN-4676-1: OpenEXR vulnerabilities

USN-4675-1: OpenStack Horizon vulnerability Pritam Singh discovered that OpenStack Horizon incorrectly validated certain parameters. An attacker could possibly use this issue to cause OpenStack Horizon to redirect to a malicious URL. Source: USN-4675-1: OpenStack Horizon vulnerability
