Test ID:1.3.6.1.4.1.25623.1.1.2.2020.1055
Category:Huawei EulerOS Local Security Checks
Title:Huawei EulerOS: Security Advisory for elfutils (EulerOS-SA-2020-1055)
Summary:The remote host is missing an update for the Huawei EulerOS 'elfutils' package(s) announced via the EulerOS-SA-2020-1055 advisory.
Description:Summary:
The remote host is missing an update for the Huawei EulerOS 'elfutils' package(s) announced via the EulerOS-SA-2020-1055 advisory.

Vulnerability Insight:
An invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl in elfutils through v0.174. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by consider_notes.(CVE-2018-18310)

An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.(CVE-2018-18520)

Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.(CVE-2018-18521)

An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is not a real issue, but instead a 'warning caused by ASAN because the allocation is big. By setting ASAN_OPTIONS=allocator_may_return_null=1 and running the reproducer, nothing happens.'(CVE-2019-7148)

Affected Software/OS:
'elfutils' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.5.0.

Solution:
Please install the updated package(s).
