Name of the Vulnerable Software and Affected Versions radare2 version 2.5.0

Description The issue allows remote attackers to cause a denial of service, resulting in a heap-based out-of-bounds read and application crash, via a crafted ELF file. This is due to a problem in the r read le32() function.

Recommendations For radare2 version 2.5.0, consider avoiding the use of the r read le32() function until a patch is available. As a temporary workaround, restrict the processing of crafted ELF files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
