Researchers at the Qualys Threat Research Unit (TRU) have unearthed discovered a critical security flaw in OpenSSH's server (sshd) in glibc-based Linux systems.
Preliminary note: OpenSSH is one of the most secure software in the
world; this vulnerability is one slip-up in an otherwise near-flawless
implementation. Its defense-in-depth design and code are a model and an
inspiration, and we thank OpenSSH’s developers for their exemplary work.
