CVE-2017-8394

Status: ModifiedHigh (7.5)—

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to an invalid read of size 4 due to NULL pointer dereferencing of _bfd_elf_large_com_section. This vulnerability causes programs that conduct an analysis of binary programs using the libbfd library, such as objcopy, to crash.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
