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 an invalid free and application crash, via a crafted ELF file. This is due to an uninitialized variable in the CPSE handler in libr/anal/p/anal avr.c.

Recommendations For radare2 version 2.5.0, consider avoiding the use of the r strbuf fini() function until a patch is available. As a temporary workaround, restrict the processing of crafted ELF files to minimize the risk of exploitation.
