pjd 2005-08-19 12:06:40 UTC FreeBSD src repository Modified files: (Branch: RELENG_5) sys/opencrypto cryptodev.c Log: MFC: sys/opencrypto/cryptodev.c 1.26 Fix bogus check. It was possible to panic the kernel by giving 0 length. This is actually a local DoS, as every user can use /dev/crypto if there is crypto hardware in the system and cryptodev.ko is loaded (or compiled into the kernel). Reported by: Mike Tancsa <mike@sentex.net> Security: Local DoS on systems with crypto HW and with /dev/crypto available Revision Changes Path 1.22.2.2 +4 -2 src/sys/opencrypto/cryptodev.c
