Title:	Huawei EulerOS: Security Advisory for binutils (EulerOS-SA-2021-2047)
Summary:	The remote host is missing an update for the Huawei EulerOS 'binutils' package(s) announced via the EulerOS-SA-2021-2047 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'binutils' package(s) announced via the EulerOS-SA-2021-2047 advisory. Vulnerability Insight: There's a flaw in the BFD library of binutils in versions before 2.36. An attacker who supplies a crafted file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system availability by way of excessive memory consumption.(CVE-2021-3487) There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.(CVE-2021-20197) Affected Software/OS: 'binutils' package(s) on Huawei EulerOS V2.0SP9(x86_64). Solution: Please install the updated package(s). CVSS Score: 7.1 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:C
