radareorg.radare2 is vulnerable to Out-of-bounds Read
33
Low Risk
This Affects:
radareorg.radare2TL;DR
Affected versions of this package contain a heap out-of-bounds read in r_bin_java_line_number_table_attr_new in the Java class parser. A short LineNumberTable attribute can pass a size check and then be read past the allocated buffer. Opening a malformed Java .class file can crash radareorg.radare2. The patch tightens the minimum size check before the attribute is parsed.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and open or analyze an untrusted Java .class file with radare2 or rabin2.
Background info
radareorg.radare2 is vulnerable to Out-of-bounds Read in versions 0.9.6 - 6.1.6.
How to fix this
Upgrade the radareorg.radare2 library to the patch version.
