Summary

Updated radare2 packages fix security vulnerabilities:
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.
