radare2 is vulnerable to Out-of-bounds Read

In radare2 through 5.3.0 there is a double free vulnerability in the pyc parse via a crafted file which can lead to DoS.

In radare2 before version 4.5.0, malformed PDB file names in the PDB server path cause shell injection. To trigger the problem it's required to open the executable in radare2 and run idpd to trigger the download. The shell code will execute, and will create a file called pwned in the current directory.

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.

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.

In radare2 before 3.9.0, a command injection vulnerability exists in bin_symbols() in libr/core/cbin.c. By using a crafted executable file, it's possible to execute arbitrary shell commands with the permissions of the victim. This vulnerability is due to an insufficient fix for CVE-2019-14745 and improper handling of symbol names embedded in executables.

In radare2 before 3.7.0, a command injection vulnerability exists in bin_symbols() in libr/core/cbin.c. By using a crafted executable file, it's possible to execute arbitrary shell commands with the permissions of the victim. This vulnerability is due to improper handling of symbol names embedded in executables.

In radare2 through 3.5.1, cmd_mount in libr/core/cmd_mount.c has a double free for the ms command.

radare2 through 3.5.1 mishandles the RParse API, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact, as demonstrated by newstr buffer overflows during replace operations. This affects libr/asm/asm.c and libr/parse/parse.c.
