EulerOS Virtualization 3.0.2.6 : binutils (EulerOS-SA-2021-1408)
medium Nessus Plugin ID 147574
Synopsis
The remote EulerOS Virtualization host is missing multiple security updates.Description
According to the versions of the binutils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :- A use after free issue exists in the Binary File Descriptor (BFD) library (aka libbfd) in GNU Binutils 2.34 in bfd_hash_lookup, as demonstrated in nm-new, that can cause a denial of service via a crafted file.(CVE-2020-16592)
- ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER.
ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: none.(CVE-2020-16598)
- A flaw exists in binutils in bfd/pef.c. An attacker who is able to submit a crafted PEF file to be parsed by objdump could cause a heap buffer overflow -> out-of-bounds read that could lead to an impact to application availability. This flaw affects binutils versions prior to 2.34.(CVE-2020-35493)
- There's a flaw in binutils /opcodes/tic4x-dis.c. An attacker who is able to submit a crafted input file to be processed by binutils could cause usage of uninitialized memory. The highest threat is to application availability with a lower threat to data confidentiality. This flaw affects binutils versions prior to 2.34.(CVE-2020-35494)
- find_abstract_instance in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32, allows remote attackers to cause a denial of service (infinite recursion and application crash) via a crafted ELF file.(CVE-2019-17450)
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.
