I've just released Linux 2.4.36-rc1.
It fixes several vulnerabilities, some of them discovered in 2.6. Among them, we find 2 ISDN overflows, one case of insufficient permissions checking on core dumps, the ability for a process to escape ptrace-based syscall policy checking, and the possibility for a specially crafted ELF binary to bypass the recently added restrictions on the minimum MMAP address.
Due to several reports of mis-compilations with GCC 4.2, I have explicitly disabled its use with an explicit message.
I got one report from Krzysztof Strasburger of a good old 386 not booting anymore due to a misplaced "HAS_TSC" in the config. His fix made perfect sense and looked good, but please complain if you notice a related problem on old hardware.
It was also not possible to build for ia32 on x86_64 due to a recent vulnerability fix in which an update to the size of the instruction was missing (cmpl -> cmpq).
I'm still planning on releasing 2.4.36 around the end of the year (eg: last week-end), if nothing new is discovered since. If new fixes are merged by that time, I may delay it a little bit to the beginning of January.
Please test it, beat it and report any problems (build or bugs).
The patch and changelog will appear soon at the following locations: ftp://ftp.all.kernel.org/pub/linux/kernel/v2.4/testing/ ftp://ftp.all.kernel.org/pub/linux/kernel/v2.4/testing/patch-2.4.36-rc1.bz2 ftp://ftp.all.kernel.org/pub/linux/kernel/v2.4/testing/patch-2.4.36.log
