CVE-2019-7665: Canonical Ubuntu Linux

Medium severity, CVSS 5.5. EPSS: 1.3% chance of exploitation in the next 30 days.

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.
