Category:	Huawei EulerOS Local Security Checks
Title:	Huawei EulerOS: Security Advisory for glibc (EulerOS-SA-2020-2019)
Summary:	The remote host is missing an update for the Huawei EulerOS 'glibc' package(s) announced via the EulerOS-SA-2020-2019 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'glibc' package(s) announced via the EulerOS-SA-2020-2019 advisory. Vulnerability Insight: An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc 2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data.(CVE-2020-6096) Affected Software/OS: 'glibc' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.6.0. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
