A vulnerability was found in radare2 through 4.0, there is an integer
overflow for the variable new_token_size in the function r_asm_massemble
at libr/asm/asm.c. This integer overflow will result in a Use-After-Free
for the buffer tokens, which can be filled with arbitrary malicious data
after the free. This allows remote attackers to cause a denial of service
(application crash) or possibly execute arbitrary code via crafted input
(CVE-2019-19590).

radare2 through 4.0.0 lacks validation of the content variable in the
function r_asm_pseudo_incbin at libr/asm/asm.c, ultimately leading to an
arbitrary write. This allows remote attackers to cause a denial of service
(application crash) or possibly have unspecified other impact via crafted
input (CVE-2019-19647).

The radare2 package has been updated to version 4.2.1, fixing these issues
and other bugs.

Also, the radare2-cutter package has been updated to version 1.10.1.");
