RHEL 6 : elfutils (Unpatched Vulnerability)

medium Nessus Plugin ID 195525

Synopsis

The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.

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.

 - 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)

 - An issue was discovered in elfutils 0.175. A segmentation fault can occur in the function elf64_xlatetom in libelf/elf32_xlatetom.c, due to dwfl_segment_report_module not checking whether the dyn data read from a core file is truncated. A crafted input can cause a program crash, leading to denial-of-service, as demonstrated by eu-stack. (CVE-2019-7150)

 - 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)

 - In elfutils 0.183, an infinite loop was found in the function handle_symtab in readelf.c .Which allows attackers to cause a denial of service (infinite loop) via crafted file. (CVE-2021-33294)

 - elfutils v0.189 was discovered to contain a NULL pointer dereference via the handle_verdef() function at readelf.c. (CVE-2024-25260)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
