The sh_op() function in radare2 2.5.0 allows remote attackers to cause a denial of service (heap-based out-of-bounds read and application crash) via a crafted ELF file.
In radare2 2.5.0, there is a heap-based buffer over-read in the r_hex_bin2str function (libr/util/hex.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted DEX file. This issue is different from CVE-2017-15368.
In radare2 2.5.0, there is a heap-based buffer over-read in the dalvik_op function (libr/anal/p/anal_dalvik.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted DEX file. Note that this issue is different from CVE-2018-8809, which was patched earlier.
