An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.35.1. A heap-based buffer over-read can occur in bfdgetlsigned32 in libbfd.c because shentsize is not validated in bfdelfslurpsecondaryrelocsection in elf.c.

A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in bfdelfslurpsecondaryrelocsection in elf.c due to the number of symbols not calculated correctly. The highest threat from this vulnerability is to system availability.
