An update for elfutils is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link (s) in the References section.
The elfutils packages contain a number of utility programs and libraries related to the creation and maintenance of executable code.
The following packages have been upgraded to a later upstream version:
elfutils (0.176). (BZ#1676504)
Security Fix(es) :
elfutils: Heap-based buffer over-read in libdw/ dwarf_getaranges.c:dwarf_getaranges() via crafted file (CVE-2018-16062)
elfutils: Double-free due to double decompression of sections in crafted ELF causes crash (CVE-2018-16402)
elfutils: Heap-based buffer over-read in libdw/dwarf_getabbrev.c and libwd/ dwarf_hasattr.c causes crash (CVE-2018-16403)
elfutils: invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl (CVE-2018-18310)
elfutils: eu-size cannot handle recursive ar files (CVE-2018-18520)
elfutils: Divide-by-zero in arlib_add_symbols function in arlib.c (CVE-2018-18521)
elfutils: heap-based buffer over-read in read_srclines in dwarf_getsrclines.c in libdw (CVE-2019-7149)
elfutils: segmentation fault in elf64_xlatetom in libelf/elf32_xlatetom.c (CVE-2019-7150)
elfutils: Out of bound write in elf_cvt_note in libelf/note_xlate.h (CVE-2019-7664)
elfutils: heap-based buffer over-read in function elf32_xlatetom in elf32_xlatetom.c (CVE-2019-7665)
