Description M Grundman 2005-02-05 00:10:18 UTC
Mozilla and Firefox provoke a kernel bug when PaX is enabled
when Paging based PAGE_EXEC and Segmentation based PAGE_EXEC are disabled the bug disappear
the bug repeat all the time for the same combination of web surfing however it cannot be reproduced all the time

the bug appears with 2.4.28-hardened-r4 and all kernel versions I tested before

Please attach your complete kernel.config

Also, try to get the translated calls (this can be done also by manually looking at the and grabbing the calls by ther addresses with gdb) using ksymoops, so, it will process the event output and translate them automatically.

After doing that, and having your .config, we will be able to trace the error and quite possibly locate the fault.

Cheers and thanks in advance,
