CVE-2021-39480: Denial of service in bingrep

The vulnerability (CWE-770) involves uncontrolled memory allocation due to untrusted input. The crash log shows an attempt to allocate 0xFFFFFFFFFFFFFFFA bytes, which suggests an integer underflow/wrap in size calculation (e.g., e_shnum * e_shentsize or similar). The ELF parser's header processing function is the most likely culprit, as it uses header fields (like e_shentsize and e_shnum) to compute allocation sizes. The POC's manipulated ELF headers (e.g., large e_shentsize) would trigger this during section/program header parsing. Without code access, this is inferred from the symptoms and standard ELF parsing patterns.
