Apache2: stack smashing attack in function logio_in

bornsilly · n00b Joined: 23 Dec 2003 Posts: 16 Location: Netherlands

Hi,

Ever since a have done a update a while ago, i am unable to connect to Apache, although the server does start it adds a entry in the error_log file with the following message "apache2: stack smashing attack in function logio_in_filter()" whenever i try to access a page.

I have removed the fstack-protector-all in my make.conf and recompiled Apache but the problem still remains.

Hope somebody can help me.

Marco.

Could you please post the output of 'emerge --info'?

I too seem to face a similar problem. Has anyone found a solution or has any ideas what to look for ?
Thanks,
Sean
