Name of the Vulnerable Software and Affected Versions Radare2 version 5.9.9

Description A problematic vulnerability was found in the function cons stack load in the library /libr/cons/cons.c of the component radiff2. The manipulation of the argument -T leads to memory corruption. An attack must be approached locally and has a rather high complexity, making exploitation difficult. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted. The parameter -T is experimental and "crashy". Further analysis has shown that "the race is not a real problem unless you use asan". A new warning has been added.

Recommendations To fix this issue, it is recommended to apply the patch named 5705d99cc1f23f36f9a84aab26d1724010b97798. As a temporary workaround, consider avoiding the use of the experimental parameter -T until the issue is resolved. Additionally, restrict access to the vulnerable function cons stack load to minimize the risk of exploitation.
