| 14 | - create a simple ia32 to risc converter for the 10 most used | ||
| 15 | instructions | ||
| 16 | - create a simple code obfuscation engine for this risc level | ||

| 21 | (from uclibc faq) | ||
| 22 | When I run 'ldd' to get a list of the library dependencies for a uClibc | ||
| 23 | binary, ldd segfaults! What should I do? | ||
| 24 | |||
| 25 | Use the ldd that is built by uClibc, not your system's one. When your | ||
| 26 | system's ldd looks for library dependencies, it actually _runs_ that program. | ||
| 27 | This works fine -- usually. It generally will not work at all when you have | ||
| 28 | been cross compiling (which is why ldd segfaults). The ldd program created by | ||
| 29 | uClibc is cross platform and doesn't even try to run the target program (like | ||
| 30 | your system one does). So use the uClibc one and it will do the right thing, | ||
| 31 | and it won't segfault even when you are cross compiling. | ||
| 32 | |||
| 33 | - maybe exploit that to gain privs when people run "ldd file" | ||
| 34 | |||
| 35 | ===== | ||
| 36 | |||
| 37 | file overflow | ||
| 38 | - write a reliable exploit that could be used to seize control (just | ||
| 39 | make eh_shentsize very large, direct stack overflow) | ||
