Description
A security vulnerability has been detected in radareorg radare2 up to 6.1.6. Affected by this vulnerability is the function r_core_bin_load of the file libr/core/cfile.c. Such manipulation leads to use after free. The attack needs to be performed locally. The exploit has been disclosed publicly and may be used. The name of the patch is 635ab1eeb30340c26076722a90cb91fb2272130b. Applying a patch is advised to resolve this issue.
A use-after-free vulnerability has been identified in Radare2, specifically in versions up to 6.1.6. The issue arises in the r_core_bin_load function within libr/core/cfile.c, where the function improperly uses a freed I/O descriptor. This vulnerability requires local exploitation. The problem occurs when the 'cmd.load' command closes the current I/O descriptor, but r_core_bin_load continues to use a cached pointer to that descriptor, leading to a heap-use-after-free error. This vulnerability has been publicly disclosed and exploited.
Users are advised to update to Radare2 version 6.1.7 or later, where this vulnerability has been patched.
