USN-3345-1: Linux kernel vulnerabilities

USN 3324-1 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. 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) 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) Jann Horn discovered that bpf in Linux kernel does not restrict the output of the printbpfinsn function. A local attacker could use this to obtain sensitive address information. (CVE-2017-9150) 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)
