radareorg.radare2 is vulnerable to Integer Overflow
33
Low Risk
This Affects:
radareorg.radare2TL;DR
Affected versions of this package contain a signed integer overflow in r_str_append and r_str_prepend in libr/util/str.c. Length arithmetic on large inputs wraps and can drive an undersized allocation. The resulting out-of-bounds access can corrupt memory or crash the process. The patch uses size_t lengths and validates before allocation.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and process input that reaches r_str_append or r_str_prepend with externally influenced string lengths.
Background info
radareorg.radare2 is vulnerable to Integer Overflow in versions 0.8.6 - 6.1.6.
How to fix this
Upgrade the radareorg.radare2 library to the patch version.
