Description Mark J. Cox 2005-08-11 07:45:49 EDT
Tim Yamin from Gentoo noticed that some older security related bugs in the
decompression code had not been fixed in the kernel.  This is fairly minor as
there are few places where the kernel decompresses arbitrary data.  However it
could be a problem for things like zisofs (if someone mounts a malicious
filesystem), perhaps cslip or ppp too).



Fix for 2.6 is here, pretty much identical for 2.4:

Comment 4 Mark J. Cox 2005-08-18 06:09:17 EDT
Sergey Vlasov has done some analysis on these issues and discovered that the
changes in file lib/zlib_inflate/inftrees.c are incorrect and in fact are not
needed.  Gentoo have agreed and therefore from the patch above please ignore the
lib/zlib_inflate/inftrees.c hunk.  This means that CAN-2005-2549 is dropped, but
CAN-2005-2548 still applies.
Comment 5 Jason Baron 2005-08-22 15:00:19 EDT
Marc, do CAN-2005-2458?
Comment 6 Jason Baron 2005-08-22 15:01:00 EDT
i meant Mark. sorry.
