AI-suggested

European organizations using Radare2 version 5.9.9 should apply the official patch identified by commit 5705d99cc1f23f36f9a84aab26d1724010b97798 to remediate the vulnerability. Given the experimental nature of the '-T' parameter, it is advisable to avoid using this argument in production or critical environments until the software is confirmed stable. Organizations should enforce strict access controls to limit local access to systems running Radare2, ensuring only authorized personnel can execute the tool. Monitoring and logging local user activities involving Radare2 can help detect any anomalous usage patterns. Additionally, integrating AddressSanitizer or similar memory debugging tools during development and testing phases can help identify potential memory corruption issues early. Regularly updating Radare2 to the latest stable versions and subscribing to security advisories related to the tool will further reduce exposure to similar vulnerabilities.

Description

A vulnerability was found in Radare2 5.9.9 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 exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The patch is named 5705d99cc1f23f36f9a84aab26d1724010b97798. It is recommended to apply a patch to fix this issue. 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.
