Name of the Vulnerable Software and Affected Versions Radare2 version 5.9.9

Description A vulnerability was found in Radare2 and classified as problematic. This issue affects the function r cons context break pop in the library /libr/cons/cons.c of the component radiff2. The manipulation of the argument -T leads to memory corruption. The attack needs to be approached locally. The complexity of an attack is rather high. The exploitation is known to be difficult. The real existence of this vulnerability is still doubted at the moment. The documentation explains that the parameter -T is experimental and "crashy". Further analysis has shown "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 a patch named 5705d99cc1f23f36f9a84aab26d1724010b97798. As a temporary workaround, consider avoiding the use of the experimental parameter -T until the issue is resolved. Additionally, users can restrict the use of the radiff2 component to minimize the risk of exploitation.
