A timing side-channel vulnerability exists in phpseclib versions prior to 3.0.51, 2.0.53, and 1.0.28 in the Net\SSH2::get_binary_packet() function. The vulnerability arises because the library uses PHP's != operator for HMAC comparison, which performs a variable-time memcmp() operation. This can potentially allow an attacker to gain sensitive information through timing analysis. The issue is fixed in the specified patched versions. Ubuntu has released security updates addressing this vulnerability in various php-phpseclib package versions.

phpseclib versions starting from 0.1.1 and prior to 3.0.51, 2.0.53, and 1.0.28 use PHP's != operator to compare SSH packet HMACs in the Net\SSH2::get_binary_packet() method. The != operator on equal-length binary strings uses memcmp(), which short-circuits on the first differing byte, resulting in a variable-time comparison (CWE-208). This timing side-channel vulnerability could allow a remote attacker to obtain sensitive information. The vulnerability is addressed by implementing constant-time comparison in the fixed versions. Ubuntu security notices confirm patches are available for multiple LTS releases.
