Name of the Vulnerable Software and Affected Versions
radare2 version 4.5.0
Description
The issue is caused by radare2 misparsing signature information in PE files, leading to a segmentation fault in the
r x509 parse algorithmidentifier function in libr/util/x509.c. This occurs due to a malformed object identifier in IMAGE DIRECTORY ENTRY SECURITY.Recommendations
For radare2 version 4.5.0, consider disabling the
r x509 parse algorithmidentifier function as a temporary workaround until a patch is available. Restrict access to the libr/util/x509.c module to minimize the risk of exploitation. Avoid processing PE files with malformed object identifiers in IMAGE DIRECTORY ENTRY SECURITY until the issue is resolved. Found an issue in the description? Have something to add?
