similar to: (Fwd) DoS for Linux 2.1.89 - 2.2.3: 0 length fragment bug

Hi All, I traced the core dump of a segfaulting tinc (1.1pre16) and found that the problem occurs when dest->mtu is 0 in src/route.c:607:fragment_ipv4_packet() maxlen = (dest->mtu - ether_size - ip_size) & ~0x7; ... int len = todo > maxlen ? maxlen : todo; memcpy(DATA(&fragment) + ether_size + ip_size, offset, len); If dest->mtu is 0, signed int maxlen becomes -40 and is

Hi all, I've just migrated my mail system from procmail to managesieve/sieve and I'm having trouble trying to duplicate a could of rules I used to use in my procmail config. One particular rule would be this: :0 Wfh * ^Sender: owner-scientific-linux-devel at LISTSERV.FNAL.GOV | (sed -e '/^Subject:/ s/\[SCIENTIFIC-LINUX-DEVEL\] *//g'| sed ':a;N;$!ba;s/Precedence:

...and another one. Of course, if you subscribed to the redhat-watch list then I wouldn't have to forward these (hint, hint). ;) Cheers, Dan ___________________________________________________________________________ Dan Yocum | Phone: (630) 840-8525 Linux/Unix System Administrator | Fax: (630) 840-6345 Computing Division OSS/FSS | email: yocum@fnal.gov

I have the xensource 3.1.0 x86_64 tarball installed over a RHEL5 clone distribution. The "ethtool" utility only returns the following information: [root@fermigrid5 etc]# ethtool eth0 Settings for eth0: Link detected: yes [root@fermigrid5 etc]# Since I have no vanilla-installed rhel5 machines with which to compare, I am not sure if I am dealing with a bug in the ethtool (whose

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this:
