Description

I searched around a bit and found some more Replicant vulnerabilities. With this issue I want to provide the patches for them.

I've merged them already to my local Replicant 4.2 repo and successfully compiled/reflashed/tested them on my i9100 (with smdk4412 kernel).

Updated by Wolfgang Wiedmeyer over 5 years ago

Thank you for the patches!
I applied the patches and cannot report any issues. I am running a build with these patches for several days now.
Kernel patches are tested with my smdk4412 kernel sources.

While we're mostly at kernel security here already: I also noticed that there is a busybox binary at usr/galaxys2_initramfs_files in the smdk4412 kernel sources.
I am not sure if this is actually used for the Galaxy S2, but if yes, it should maybe build from source. It could also be replaced with the one from external/busybox that already gets build. The binary gets at least included in the stage1 directory of initramfs_data.cpio.

#3

Updated by Wolfgang Wiedmeyer over 5 years ago

I did a clean merge of the current Replicant 4.2 branch with the cm-13.0 branch and I noticed a few things when I tried to apply the changes on top for the smdk4412 kernel.

First off: Can patch 0002 really be applied to the 3.0.x kernel? I noticed that it was not backported to the 3.2 kernel. I did not find the commit in there and the relevant code is also not there: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/net/ipv4/tcp_cubic.c?h=linux-3.2.y#n153

A few changes are already included in Cyanogenmod 13 (e.g. patch 0013). For CVE-2013-6282 (patch 0007) a different patch was included in Cyanogenmod: https://github.com/CyanogenMod/android_kernel_samsung_smdk4412/commit/67f8047290499070df082f5a2de81a387cfcfdd6

The rest of the kernel patches applied nicely.
