phpseclib has a variable-time HMAC comparison in SSH2::get_binary_packet() using != instead of hash_equals()

phpseclib SSH2: Variable-time comparison in HMAC verification Summary phpseclib\Net\SSH2::getbinarypacket uses PHP's != operator to compare a received SSH packet HMAC against the locally computed HMAC. != on equal-length binary strings in PHP uses memcmp, which short-circuits on the first differi...

cmd/cgo: Go cgo: Code smuggling due to comment parsing discrepancy

A flaw was found in Go's 'cgo tool'. This vulnerability arises from a discrepancy in how Go and C/C++ comments are parsed, which allows for malicious code to be hidden within comments and then "smuggled" into the compiled cgo binary. An attacker could exploit this to embed and execute arbitrary...

binutils: Binutils: Denial of Service via crafted ELF binary processing

A flaw was found in binutils. An attacker could exploit this vulnerability by providing a crafted Executable and Linkable Format ELF binary with malformed relocation or symbol data. Processing this malicious binary leads to an invalid pointer free, which triggers memory corruption checks and caus...
