[8.930][BUG] snort Segfault

Hi All

I got a kernel segfault with 8.930

Hi Cristof

Just to make it easier to report back if there are any issues? What was the pattern update number and how can we check that we already have the required engine?

I think this is important to check before posting back [:)]

Thanks

Hi wingman,

please check if the following command returns the current ipsbundle-version:

skywalker:/root # rpm -qa | grep ipsbundle
u2d-ipsbundle-9-37

Cheers,
Cristof

Just a hint to help debugging, the ips is currently logging in UTC and not in localtime. It's be tracked as Mantis 21210.

Hi,

Just happened again in 8.940013 during streaming of videocontent. Web Filtering is disabled, but application control is enabled.

2012:04:29-11:55:53 firewall kernel: [28691.932488] snort_inline[4554]: segfault at 44eecf00 ip 00000000f6c8efba sp 00000000ff82cbc0 error 4 in web-client.so[f6c85000+14000]

I do have the latest pattern version:

firewall:/home/login # rpm -qa | grep ipsbundle
u2d-ipsbundle-9-37

Franc.

An IPS issue, but nothing in the kernel log.

I had nothing logged in the IPS log when the segfault occurred.

Hi Ian,

If the system that is segfaulting is a VM, maybe try adding a serial port to it and send the output to a text file. I used that last beta and it should get more info.

Hi Paul,
both UTMs are hardware, the ACC is running on VM.

Ian that sounds a different issue than the segfault error. Maybe open a new thread?

Updated

I have opened a new thread to track this. Please post updates here

Could you please check the /var/storage/cores/
directory for any snort core dumps, and then email one of those
to fwestphal@astaro.com?

Thanks.
