MEDIUM 5.5EPSS 1.31%
Does this matter?
Lower severity and a low EPSS score (1.31%). Track it; it rarely justifies an emergency change on its own.
Description
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.
