EulerOS 2.0 SP3 : kernel (EulerOS-SA-2018-1406)
high Nessus Plugin ID 119565
Synopsis
The remote EulerOS host is missing multiple security updates.Description
According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :- Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members.(CVE-2018-13405)
- fuse-backed file mmap-ed onto process cmdline arguments causes denial of service.(CVE-2018-1120)
- The timer_create syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent-sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/PID/timers is read). This allows userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE).(CVE-2017-18344)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
