Hi, FreeBSD-SA-14:17.kmem describes kernel memory disclosures in SCTP control messages: http://security.freebsd.org/advisories/FreeBSD-SA-14:17.kmem.asc > [...] the process may be able to retrieve 2 bytes of kernel memory > for all three control messages, plus 92 bytes for SCTP_SNDRCV and 76 > bytes for SCTP_EXTRCV. If the local process is permitted to receive > SCTP notification, a maximum of 112 bytes of kernel memory may be > returned to userland. I think this affects all our kernels including 8.3 and 9.0 in wheezy. I'm not sure if SCTP must be configured by a superuser first, but for now I'll assume any nonprivileged user might be able to exploit this. -- System Information: Debian Release: 7.1 APT prefers proposed-updates APT policy: (500, 'proposed-updates'), (500, 'stable') Architecture: kfreebsd-amd64 (x86_64) Kernel: kFreeBSD 9.0-2-amd64-xenhvm-ipsec Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
