Radare 2

Radare2 has a division by zero vulnerability in Mach-O parser's rebase_buffer function. This allow attackers to create malicious inputs that can cause denial of service.

Radare2 has a use-after-free vulnerability in pyc parser's get_none_object function. Attacker can read freed memory afterwards. This will allow attackers to cause denial of service.

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 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.

The grub_memmove function in shlr/grub/kern/misc.c in radare2 1.5.0 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted binary file, possibly related to a read overflow in the grub_disk_read_small_real function in kern/disk.c in GNU GRUB 2.02.

The relocs function in libr/bin/p/bin_bflt.c in radare2 1.2.1 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted binary file.

The grub_memmove function in shlr/grub/kern/misc.c in radare2 1.5.0 allows remote attackers to cause a denial of service (stack-based buffer underflow and application crash) or possibly have unspecified other impact via a crafted binary file, possibly related to a buffer underflow in fs/ext2.c in GNU GRUB 2.02.

The dalvik_disassemble function in libr/asm/p/asm_dalvik.c in radare2 1.2.1 allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted DEX file.

In radare2 through 3.5.1, there is a heap-based buffer over-read in the r_egg_lang_parsechar function of egg_lang.c. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact because of missing length validation in libr/egg/egg.c.

In radare2 through 3.5.1, the rcc_context function of libr/egg/egg_lang.c mishandles changing context. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact (invalid memory access in r_egg_lang_parsechar; invalid free in rcc_pusharg).

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.

The wasm_dis function in libr/asm/arch/wasm/wasm.c in radare2 2.0.0 allows remote attackers to cause a denial of service (stack-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted WASM file that triggers an incorrect r_hex_bin2str call.

The dex_parse_debug_item function in libr/bin/p/bin_dex.c in radare2 1.2.1 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted DEX file.

In radare2 2.0.1, an integer exception (negative number leading to an invalid memory access) exists in store_versioninfo_gnu_verdef() in libr/bin/format/elf/elf.c via crafted ELF files when parsing the ELF version on 32bit systems.
