CVE-2019-12972
Last modified
CVE-2019-12972 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character.. EPSS estimates a 1.80% chance of exploitation in the next 30 days.
