1 | Hi, |
2 | I'm looking for a way to reduce glibc code size. |
3 | It can be a way to make system smaller and minimize the impact |
4 | of attack vectors in glibc, as in return-to-libc attack. |
5 | |
6 | Lets say I'm deleting the program 'mkdir', and mkdir uses a function |
7 | in glibc that non of the other parts of the system uses. |
8 | Then I want to eliminate this function from glibc. This leads to smaller |
9 | code and if this function is used in some attack scenario, maybe prevent it. |
10 | |
11 | Is there a way to do it? |
12 | Can you help me think how to build a tool like this? or, integrate |
13 | with existing tools. |
14 | |
15 | Thanks, |
16 | Kfir |
