EulerOS 2.0 SP2 : elfutils (EulerOS-SA-2019-2510)

medium Nessus Plugin ID 131663

Language:

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the elfutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

 - **DISPUTED** An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is not a real issue, but instead a 'warning caused by ASAN because the allocation is big.
 By setting ASAN_OPTIONS=allocator_may_return_null=1 and running the reproducer, nothing happens.'(CVE-2019-7148)

 - A heap-based buffer over-read was discovered in the function read_srclines in dwarf_getsrclines.c in libdw in elfutils 0.175. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by eu-nm.(CVE-2019-7149)

 - 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 heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes.(CVE-2019-7665)

 - 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)

 - 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)

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.

Solution

Update the affected elfutils packages.
