CVE-2018-20458
In radare2 prior to 3.1.1, r_bin_dyldcache_extract in libr/bin/format/mach0/dyldcache.c may allow attackers to cause a denial-of-service (application crash caused by out-of-bounds read) by crafting an input file.
Does this matter?
Lower severity and a low EPSS score (0.95%). Track it; it rarely justifies an emergency change on its own.
