An update for elfutils is now available for Red Hat Enterprise Linux 8.
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#1683705)
Security Fix(es) :
elfutils: buffer over-read in the ebl_object_note function in eblobjnote.c in libebl (CVE-2019-7146)
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)
