New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- A flaw was found in the Linux kernel's client-side implementation of the cifs protocol. This flaw allows an attacker controlling the server to kernel panic a client which has the CIFS server mounted.(CVE-2018-1066)
- Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel allows local users to cause a denial of service (kernel memory exhaustion) via multiple read accesses to files in the /sys/class/sas_phy directory.(CVE-2018-7757)
- A race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel allows local users to cause a denial of service (panic) by leveraging root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck (cpu number) directory.(CVE-2018-7995)
- Improper validation in the bnx2x network card driver of the Linux kernel version 4.15 can allow for denial of service (DoS) attacks via a packet with a gso_size larger than ~9700 bytes. Untrusted guest VMs can exploit this vulnerability in the host machine, causing a crash in the network card.(CVE-2018-1000026)
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.
