radareorg.radare2 is vulnerable to Integer Overflow
33
Low Risk
This Affects:
radareorg.radare2TL;DR
Affected versions of this package contain an integer overflow in r_str_word_get0set in libr/util/str.c. Word-count arithmetic over externally influenced input wraps and yields an incorrect buffer size. The subsequent out-of-bounds access corrupts memory or crashes radareorg.radare2. The patch adds bounds validation to the word-splitting logic.
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_word_get0set with externally influenced lengths.
Background info
radareorg.radare2 is vulnerable to Integer Overflow in versions 0.9.6 - 6.1.6.
How to fix this
Upgrade the radareorg.radare2 library to the patch version.
