Titel:	Ubuntu: Security Advisory for linux (USN-4527-1)
Zusammenfassung:	The remote host is missing an update for the 'linux'; package(s) announced via the USN-4527-1 advisory.
Beschreibung:	Summary: The remote host is missing an update for the 'linux' package(s) announced via the USN-4527-1 advisory. Vulnerability Insight: It was discovered that the Connexant 23885 TV card device driver for the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19054) It was discovered that the Atheros HTC based wireless driver in the Linux kernel did not properly deallocate in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19073, CVE-2019-19074) Yue Haibing discovered that the Linux kernel did not properly handle reference counting in sysfs for network devices in some situations. A local attacker could possibly use this to cause a denial of service. (CVE-2019-20811) It was discovered that the F2FS file system in the Linux kernel did not properly perform bounds checking in some situations, leading to an out-of- bounds read. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2019-9445) It was discovered that the F2FS file system in the Linux kernel did not properly validate xattr meta data in some situations, leading to an out-of- bounds read. An attacker could use this to construct a malicious F2FS image that, when mounted, could expose sensitive information (kernel memory). (CVE-2019-9453) It was discovered that the F2FS file system implementation in the Linux kernel did not properly perform bounds checking on xattrs in some situations. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2020-0067) It was discovered that the NFS client implementation in the Linux kernel did not properly perform bounds checking before copying security labels in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212) Affected Software/OS: 'linux' package(s) on Ubuntu 16.04 LTS. Solution: Please install the updated package(s). CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
