CVE-2022-1451

Memory disclosure or crash via Java attribute parsing

Published Apr 24, 2022 · Updated Aug 3, 2024

Out-of-bounds read in radare2 before 5.7.0 allows attackers to expose process memory or crash the tool via a crafted Java class file. The r_bin_java_constant_value_attr_new function reads a two-byte constant-value index without first verifying that enough attribute-buffer data remains. Exploitation requires a user to open or analyze the malicious file, and the demonstrated consequences are memory disclosure or a process crash.
