According to the versions of the binutils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
A flaw was found in bfd_pef_parse_function_stubs 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.(CVE-2020-35507)
A flaw was found 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.(CVE-2020-35496)
A flaw was found in binutils. 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.(CVE-2020-35495)
There’s a flaw in the BFD library of binutils. An attacker who supplies a crafted file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system availability by way of excessive memory consumption.(CVE-2021-3487)
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.
