Vulnerabilities

A vulnerability was detected in radareorg radare2 up to 6.1.6. Affected by this issue is some unknown functionality of the file libr/bin/format/mdmp/mdmp.c of the component Memory64ListStream Parser. Performing a manipulation results in stack-based buffer overflow. The attack requires a local approach. The exploit is now public and may be used. The patch is named 175d4addb68981331c85b10681c2161c38fb5762. It is suggested to install a patch to address this issue.

A security flaw has been discovered in radareorg radare2 up to 6.1.6. This issue affects the function r_bin_java_inner_classes_attr_calc_size of the file shlr/java/class.c of the component RBinJava Line Number Table Parser. Performing a manipulation results in heap-based buffer overflow. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. The patch is named cd62d15a6cbecdc67fd03f3ebdbbbeb741d18f87. To fix this issue, it is recommended to deploy a patch.

radare2 6.1.5 contains a use-after-free vulnerability in the gdbr_threads_list() 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-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 r2_cmd_str(). Attackers can inject shell metacharacters through the jsonrpc interface parameters to achieve remote code execution on the host running radare2-mcp without requiring authentication.

radare2 prior to 6.1.4 contains a path traversal vulnerability in project deletion that allows local attackers to recursively delete arbitrary directories by supplying absolute paths that escape the configured dir.projects root directory. Attackers can craft absolute paths to project marker files outside the project storage boundary to cause recursive deletion of attacker-chosen directories with permissions of the radare2 process, resulting in integrity and availability loss.

radare2 prior to 6.1.4 contains a command injection vulnerability in the PDB parser's print_gvars() 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.

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 DW_TAG_formal_parameter 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 print_gvars() 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.

A NULL pointer dereference vulnerability was discovered in radare2 6.0.5 and earlier within the info() function of bin_ne.c. A crafted binary input can trigger a segmentation fault, leading to a denial of service when the tool processes malformed data.

radare2 v5.9.8 and before contains a memory leak in the function r2r_subprocess_init.

radare2 v.5.9.8 and before contains a memory leak in the function _load_relocations.

A vulnerability was found in Radare2 5.9.9. It has been classified as problematic. Affected is the function r_cons_pal_init in the library /libr/cons/pal.c of the component radiff2. The manipulation of the argument -T leads to memory corruption. An attack has to be approached locally. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The name of the patch is 5705d99cc1f23f36f9a84aab26d1724010b97798. It is recommended to apply a patch to fix this issue. The documentation explains that the parameter -T is experimental and "crashy". Further analysis has shown "the race is not a real problem unless you use asan". A new warning has been added.

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.

Out-of-bounds Write vulnerability in radareorg radare2 allows heap-based buffer over-read or buffer overflow.This issue affects radare2: before <5.9.9.

A vulnerability, which was classified as problematic, was found in radare2 5.9.9 33286. Affected is an unknown function in the library /libr/main/rasm2.c of the component rasm2. The manipulation leads to memory corruption. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. Upgrading to version 6.0.0 is able to address this issue. The patch is identified as c6c772d2eab692ce7ada5a4227afd50c355ad545. It is recommended to upgrade the affected component.

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 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​

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

An issue in radare2 v5.8.0 through v5.9.4 allows a local attacker to cause a denial of service via the __bf_div function.

An issue in radareorg radare2 v.0.9.7 through v.5.8.6 and fixed in v.5.8.8 allows a local attacker to cause a denial of service via the grub_sfs_read_extent function.

radare2 5.8.9 has an out-of-bounds read in r_bin_object_set_items in libr/bin/bobj.c, causing a crash in r_read_le32 in libr/include/r_endian.h.

An out-of-bounds read in radare2 v.5.8.9 and before exists in the print_insn32_fpu function of libr/arch/p/nds32/nds32-dis.h.
