Integer overflow in the rdsrdmapages function in net/rds/rdma.c in the Linux kernel allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a crafted iovec struct in a Reliable Datagram Sockets (RDS) request, which triggers a buffer overflow.
DISPUTED lxsession-logout in lxsession in LXDE, as used on SUSE openSUSE 11.3 and other platforms, does not lock the screen when the Suspend or Hibernate button is pressed, which might make it easier for physically proximate attackers to access an unattended laptop via a resume action. NOTE: there is no general agreement that this is a vulnerability, because separate control over locking can be an equally secure, or more secure, behavior in some threat environments.
Multiple buffer overflows in the Novell Client novfs module for the Linux kernel in SUSE Linux Enterprise 11 SP1 and openSUSE 11.3 allow local users to gain privileges via unspecified vectors.
An exploit was posted to full-disclosure labelled "Apache Killer". This script creates a number of threads that use multiple Range headers to exhaust memory on the Apache server.
The ASF httpd development team are working on a fix for this issue: http://www.gossamer-threads.com/lists/apache/dev/401638
