Huawei EulerOS: Security Advisory for kernel (EulerOS-SA-2019-1187)

The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2019-1187 advisory.

A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial of service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely.CVE-2018-14633

'kernel' package(s) on Huawei EulerOS Virtualization 2.5.4.

Checks if a vulnerable package version is present on the target host.

Please install the updated package(s).
