Description Stanislav Brabec 2005-09-26 15:17:06 UTC

At least on AMD64, first start of lineakconfig does not work.

brabec@hammer:~> lineakconfig
*** buffer overflow detected ***: lineakconfig terminated
Aborted

Note: this bug is not related to my last change - forcing of GTK2. But I was not
able to check whether my last change works because of this bug.

code is: 
        dfile = malloc( (strlen(CONFDIR) + 1 + strlen("/etc/") +1) * 
sizeof(char)); 
        sprintf(dfile,"%s/%s", "/etc/", DEFFILE); 
 
probably CONFDIR should be DEFFILE in line 1, or the other way round

Comment 2 Stefan Behlert 2005-12-05 15:49:13 UTC

I updated the whole lineak-bunch today to the new version. A fix for the problem above was added during this operation. After autobuild has crunched the package please update.
Even with this fix I had one segfault in lineakd itself, but it was not reproduceable.
Lineakd might be dropped for 10.2 and replaced by ial & co
