Out-of-bounds Write in radare2

Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in radareorg radare2 allows Overflow Buffers.This issue affects radare2: before <5.9.9.

Radare2 has a division by zero vulnerability in Mach-O parser's rebasebuffer 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 getnoneobject function. Attacker can read freed memory afterwards. This will allow attackers to cause denial of service.

Buffer Overflow vulnerability in radarorg radare2 v.5.8.8 allows an attacker to execute arbitrary code via the name, type, or group fields.

A heap buffer overflow vulnerability in the rasmswfdisass function of Radare2-extras before commit e74a93c allows attackers to execute arbitrary code or carry out denial of service (DOS) attacks.

An out-of-bounds read in radare2 v.5.8.9 and before exists in the printinsn32 function of libr/arch/p/nds32/nds32-dis.h.

An out-of-bounds read in radare2 v.5.8.9 and before exists in the printinsn32fpu function of libr/arch/p/nds32/nds32-dis.h.

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-mcp version 1.6.0 and earlier contains an os command injection vulnerability that allows remote attackers to execute arbitrary commands by bypassing the command filter through shell metacharacters in user-controlled input passed to r2cmdstr(). Attackers can inject shell metacharacters through the jsonrpc interface parameters to achieve remote code execution on the host running radare2-mcp without requiring authentication.

Out-of-bounds read in rbinnegetrelocs function in GitHub repository radareorg/radare2 prior to 5.6.8. This vulnerability may allow attackers to read sensitive information or cause a crash.

Out-of-bounds Read in rbinnegetentrypoints function in GitHub repository radareorg/radare2 prior to 5.6.8. This vulnerability may allow attackers to read sensitive information or cause a crash.

Out-of-bounds Read in GitHub repository radareorg/radare2 prior to 5.7.0.

A double free issue was discovered in radare2 in cmdinfo.c:cmdinfo(). Successful exploitation could lead to modification of unexpected memory locations and potentially causing a crash.

Heap-based Buffer Overflow in GitHub repository radareorg/radare2 prior to 5.9.0.

radare2 6.1.5 contains a use-after-free vulnerability in the gdbrthreadslist() function that allows remote attackers to trigger memory corruption by sending a valid qfThreadInfo response followed by a malformed qsThreadInfo response. Attackers can exploit this vulnerability through GDB remote debugging to cause a denial of service or potentially achieve code execution by manipulating thread list processing.

radare2 6.1.5 contains a use-after-free vulnerability in the gdbrpidslist() function within the GDB client core that allows remote attackers to cause a denial of service or potentially execute arbitrary code by sending malformed thread information responses. Attackers can trigger the vulnerability by causing qsThreadInfo to fail after qfThreadInfo successfully allocates RDebugPid structures, resulting in double-free memory corruption when the error path attempts to clean up the list.

A flaw was found in Radare2, which contains a command injection vulnerability caused by insufficient input validation when handling Pebble Application files. Maliciously crafted inputs can inject shell commands during command parsing, leading to unintended behavior during file processing​

radare2 prior to commit bc5a890 contains a command injection vulnerability in the afsv/afsvj command path where crafted ELF binaries can embed malicious r2 command sequences as DWARF DWTAGformalparameter names. Attackers can craft a binary with shell commands in DWARF parameter names that execute when radare2 analyzes the binary with aaa and subsequently runs afsvj, allowing arbitrary shell command execution through the unsanitized parameter interpolation in the pfq command string.

radare2 prior to version 6.1.4 contains a command injection vulnerability in the PDB parser's printgvars() function that allows attackers to execute arbitrary commands by embedding a newline byte in the PE section header name field. Attackers can craft a malicious PDB file with specially crafted section names to inject r2 commands that are executed when the idp command processes the file.

radare2 prior to 6.1.4 contains a command injection vulnerability in the PDB parser's printgvars() function that allows attackers to execute arbitrary commands by crafting a malicious PDB file with newline characters in symbol names. Attackers can inject arbitrary radare2 commands through unsanitized symbol name interpolation in the flag rename command, which are then executed when a user runs the idp command against the malicious PDB file, enabling arbitrary OS command execution through radare2's shell execution operator.

Buffer Overflow vulnerability in radarorg radare2 v.5.8.8 allows an attacker to execute arbitrary code via the parsedie function.

In radare2 through 4.0, there is an integer overflow for the variable newtokensize in the function rasmmassemble 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 3.7.0, a command injection vulnerability exists in binsymbols() 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, there is a heap-based buffer over-read in the regglangparsechar function of egglang.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 radare 2.0.1, a memory corruption vulnerability exists in storeversioninfognuverdef() and storeversioninfognuverneed() in libr/bin/format/elf/elf.c, as demonstrated by an invalid free. This error is due to improper shsize validation when allocating memory.

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