| Description: | Summary:
The remote host is missing an update for the 'dwarves and elfutils' package(s) announced via the SUSE-SU-2022:2614-1 advisory.
Vulnerability Insight:
This update for dwarves and elfutils fixes the following issues:
elfutils was updated to version 0.177 (jsc#SLE-24501):
elfclassify: New tool to analyze ELF objects.
readelf: Print DW_AT_data_member_location as decimal offset. Decode
DW_AT_discr_list block attributes.
libdw: Add DW_AT_GNU_numerator, DW_AT_GNU_denominator and DW_AT_GNU_bias.
libdwelf: Add dwelf_elf_e_machine_string. dwelf_elf_begin now only
returns NULL when there is an error reading or decompressing a file. If
the file is not an ELF file an ELF handle of type ELF_K_NONE is returned.
backends: Add support for C-SKY.
Update to version 0.176:
build: Add new --enable-install-elfh option. Do NOT use this for system
installs (it overrides glibc elf.h).
backends: riscv improved core file and return value location support.
Fixes:
- CVE-2019-7146, CVE-2019-7148, CVE-2019-7149, CVE-2019-7664 -
CVE-2019-7150: dwfl_segment_report_module doesn't check whether the
dyn data read from core file is truncated (bsc#1123685)
- CVE-2019-7665: NT_PLATFORM core file note should be a zero terminated
string (CVE is a bit misleading, as this is not a bug in libelf as
described) (bsc#1125007)
Update to version 0.175:
readelf: Handle multiple .debug_macro sections. Recognize and parse GNU
Property, NT_VERSION and GNU Build Attribute ELF Notes.
strip: Handle SHT_GROUP correctly. Add strip --reloc-debug-sections-only
option. Handle relocations against GNU compressed sections.
libdwelf: New function dwelf_elf_begin.
libcpu: Recognize bpf jump variants BPF_JLT, BPF_JLE, BPF_JSLT and
BPF_JSLE. backends: RISCV handles ADD/SUB relocations. Handle
SHT_X86_64_UNWIND.
- CVE-2018-18521: arlib: Divide-by-zero vulnerabilities in the function
arlib_add_symbols() used by eu-ranlib (bsc#1112723)
- CVE-2018-18310: Invalid Address Read problem in
dwfl_segment_report_module.c (bsc#1111973)
- CVE-2018-18520: eu-size: Bad handling of ar files inside are files
(bsc#1112726)
Update to version 0.174:
libelf, libdw and all tools now handle extended shnum and shstrndx
correctly.
elfcompress: Don't rewrite input file if no section data needs updating.
Try harder to keep same file mode bits (suid) on rewrite.
strip: Handle mixed (out of order) allocated/non-allocated sections.
unstrip: Handle SHT_GROUP sections.
backends: RISCV and M68K now have backend implementations to generate
CFI based backtraces.
Fixes:
- CVE-2018-16402: libelf: denial of service/double free on an attempt to
decompress the same section twice (bsc#1107066) Double-free crash in
nm and readelf
- CVE-2018-16403: heap buffer overflow in readelf (bsc#1107067)
- CVE-2018-16062: heap-buffer-overflow in
/elfutils/libdw/dwarf_getaranges.c:156 (bsc#1106390)
Update to version 0.173:
More fixes for crashes and hangs found by afl-fuzz. In particular
various functions now detect and break infinite loops caused by bad DIE
tree cycles.
