EulerOS 2.0 SP5 : elfutils (EulerOS-SA-2019-2523)

medium Nessus Plugin ID 131797

Synopsis

The remote EulerOS host is missing a security update.

Description

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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected elfutils package.
