Description

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - nasm: double-free vulnerability in pp_tokline asm/preproc.c (CVE-2020-24978)

 - In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote attackers to cause a denial of service (heap- based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
 (CVE-2017-11111)

 - In Netwide Assembler (NASM) 2.14rc0, there is an illegal address access in the function paste_tokens() in preproc.c, aka a NULL pointer dereference. It will lead to remote denial of service. (CVE-2017-14228)

 - In Netwide Assembler (NASM) 2.14rc0, there is a SEGV on unknown address that will cause a remote denial of service attack, because asm/preproc.c mishandles macro calls that have the wrong number of arguments.
 (CVE-2017-17810)

 - In Netwide Assembler (NASM) 2.14rc0, there is a heap-based buffer overflow that will cause a remote denial of service attack, related to a strcpy in paste_tokens in asm/preproc.c, a similar issue to CVE-2017-11111. (CVE-2017-17811)

 - In Netwide Assembler (NASM) 2.14rc0, there is an illegal address access in the function find_cc() in asm/preproc.c that will cause a remote denial of service attack, because pointers associated with skip_white_ calls are not validated. (CVE-2017-17819)

 - In Netwide Assembler (NASM) 2.14rc0, there is a use-after-free in pp_list_one_macro in asm/preproc.c that will lead to a remote denial of service attack, related to mishandling of operand-type errors.
