Name of the Vulnerable Software and Affected Versions radare2 version 2.0.1

Description The issue exists in the store versioninfo gnu verdef() function in libr/bin/format/elf/elf.c, where an integer exception occurs due to a negative number leading to an invalid memory access. This happens when parsing crafted ELF files on 32-bit systems.

Recommendations For radare2 version 2.0.1, consider avoiding the use of crafted ELF files to minimize the risk of exploitation until a patch is available. As a temporary workaround, restrict access to the store versioninfo gnu verdef() function in libr/bin/format/elf/elf.c to prevent invalid memory access.
