"According to the version of the elfutils packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :
- **DISPUTED** 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)
