According to the versions of the gdb packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
An issue was discovered in GNU Binutils 2.34. It is a memory leak when process microblaze-dis.c. This one will consume memory on each insn disassembled. (CVE-2020-21490)
GNU Binutils before 2.34 has an uninitialized-heap vulnerability in function tic4x_print_cond (file opcodes/tic4x-dis.c) which could allow attackers to make an information leak. (CVE-2020-35342)
GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the function bfd_dwarf2_find_nearest_line_with_alt at dwarf2.c. The attacker could supply a crafted ELF file and cause a DNS attack. (CVE-2022-48064)
GNU Binutils before 2.40 was discovered to contain a memory leak vulnerability var the function find_abstract_instance in dwarf2.c. (CVE-2022-48065)
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.
