The remote Redhat Enterprise Linux 5 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.
elfutils: eu-size cannot handle recursive ar files (CVE-2018-18520)
elfutils: heap-based buffer over-read in function elf32_xlatetom in elf32_xlatetom.c (CVE-2019-7665)
The allocate_elf function in common.h in elfutils before 0.168 allows remote attackers to cause a denial of service (crash) via a crafted ELF file, which triggers a memory allocation failure. (CVE-2016-10254)
The __libelf_set_rawdata_wrlock function in elf_getdata.c in elfutils before 0.168 allows remote attackers to cause a denial of service (crash) via a crafted (1) sh_off or (2) sh_size ELF header value, which triggers a memory allocation failure. (CVE-2016-10255)
The handle_gnu_hash function in readelf.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file. (CVE-2017-7607)
The ebl_object_note_type_name function in eblobjnotetypename.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file.
(CVE-2017-7608)
elf_compress.c in elfutils 0.168 does not validate the zlib compression factor, which allows remote attackers to cause a denial of service (memory consumption) via a crafted ELF file. (CVE-2017-7609)
The check_group function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file. (CVE-2017-7610)
The check_symtab_shndx function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file. (CVE-2017-7611)
The check_sysv_hash function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file. (CVE-2017-7612)
elflint.c in elfutils 0.168 does not validate the number of sections and the number of segments, which allows remote attackers to cause a denial of service (memory consumption) via a crafted ELF file.
(CVE-2017-7613)
dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file. (CVE-2018-16062)
libdw in elfutils 0.173 checks the end of the attributes list incorrectly in dwarf_getabbrev in dwarf_getabbrev.c and dwarf_hasattr in dwarf_hasattr.c, leading to a heap-based buffer over-read and an application crash. (CVE-2018-16403)
An invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl in elfutils through v0.174. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by consider_notes. (CVE-2018-18310)
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled. (CVE-2018-18521)
In elfutils 0.175, a negative-sized memcpy is attempted in elf_cvt_note in libelf/note_xlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash). (CVE-2019-7664)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
