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.

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.
