CVE-2018-11383
The r_strbuf_fini() function in radare2 2.5.0 allows remote attackers to cause a denial of service (invalid free and application crash) via a crafted ELF file because of an uninitialized variable in the CPSE handler in libr/anal/p/anal_avr.c.
Does this matter?
Lower severity and a low EPSS score (1.13%). Track it; it rarely justifies an emergency change on its own.
