USN-3377-1: Linux kernel vulnerabilities

First published: Thu Aug 03 2017(Updated: )

Fan Wu and Shixiong Zhao discovered a race condition between inotify events and vfs rename operations in the Linux kernel. An unprivileged local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2017-7533) It was discovered that the Linux kernel did not properly restrict RLIMIT_STACK size. A local attacker could use this in conjunction with another vulnerability to possibly execute arbitrary code. (CVE-2017-1000365) 李强 discovered that the Virtio GPU driver in the Linux kernel did not properly free memory in some situations. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-10810) 石磊 discovered that the RxRPC Kerberos 5 ticket handling code in the Linux kernel did not properly verify metadata. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7482)
