EulerOS Virtualization 2.5.2 : kernel (EulerOS-SA-2018-1370)
Medium Nessus Plugin ID 119061
SynopsisThe remote EulerOS Virtualization host is missing a security update.
DescriptionAccording to the version of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :
- A flaw was found in the Linux Kernel in the ucma_leave_multicast() function in drivers/infiniband/core/ucma.c which allows access to a certain data structure after freeing it in ucma_process_join(). This allows an attacker to cause a use-after-free bug and to induce kernel memory corruption, leading to a system crash or other unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2018-14734)
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.
SolutionUpdate the affected kernel package.
