Alpine: libasm, multiple elfutils packages: security update to 0.176-r0

medium Tenable Cloud Security Plugin ID 423880

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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)

- In elfutils 0.175, there is a buffer over-read in the ebl_object_note function in eblobjnote.c in libebl.
Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted elf file, as
demonstrated by eu-readelf. (CVE-2019-7146)

- 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)
