EulerOS Virtualization 3.0.2.2 : bindutils (EulerOS-SA-2021-2128)

medium Nessus Plugin ID 151388

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the bindutils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - 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)

 - 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)

 - 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)

 - 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)

 - There's a flaw in binutils /bfd/pef.c. An attacker who is able to submit a crafted input file to be processed by the objdump program could cause a null pointer dereference. The greatest threat from this flaw is to application availability. This flaw affects binutils versions prior to 2.34.(CVE-2020-35495)

 - There's a flaw in bfd_pef_scan_start_address() of bfd/pef.c in binutils which could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The greatest threat of this flaw is to application availability. This flaw affects binutils versions prior to 2.34.(CVE-2020-35496)

 - There's a flaw in bfd_pef_parse_function_stubs of bfd/pef.c in binutils in versions prior to 2.34 which could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The greatest threat of this flaw is to application availability.(CVE-2020-35507)
