USN-3342-1: Linux kernel vulnerabilities

First published: Thu Jun 29 2017(Updated: )

USN 3326-1 fixed a vulnerability in the Linux kernel. However, that fix introduced regressions for some Java applications. This update addresses the issue. We apologize for the inconvenience. It was discovered that a use-after-free flaw existed in the filesystem encryption subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-7374) Roee Hay discovered that the parallel port printer driver in the Linux kernel did not properly bounds check passed arguments. A local attacker with write access to the kernel command line arguments could use this to execute arbitrary code. (CVE-2017-1000363) Ingo Molnar discovered that the VideoCore DRM driver in the Linux kernel did not return an error after detecting certain overflows. A local attacker could exploit this issue to cause a denial of service (OOPS). (CVE-2017-5577) Li Qiang discovered that an integer overflow vulnerability existed in the Direct Rendering Manager (DRM) driver for VMWare devices in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7294) It was discovered that a double-free vulnerability existed in the IPv4 stack of the Linux kernel. An attacker could use this to cause a denial of service (system crash). (CVE-2017-8890) Andrey Konovalov discovered an IPv6 out-of-bounds read error in the Linux kernel's IPv6 stack. A local attacker could cause a denial of service or potentially other unspecified problems. (CVE-2017-9074) Andrey Konovalov discovered a flaw in the handling of inheritance in the Linux kernel's IPv6 stack. A local user could exploit this issue to cause a denial of service or possibly other unspecified problems. (CVE-2017-9075) It was discovered that dccp v6 in the Linux kernel mishandled inheritance. A local attacker could exploit this issue to cause a denial of service or potentially other unspecified problems. (CVE-2017-9076) It was discovered that the transmission control protocol (tcp) v6 in the Linux kernel mishandled inheritance. A local attacker could exploit this issue to cause a denial of service or potentially other unspecified problems. (CVE-2017-9077) It was discovered that the IPv6 stack in the Linux kernel was performing its over write consistency check after the data was actually overwritten. A local attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2017-9242)
