Vulnerabilities

A double free vulnerability exists in librz/bin/format/le/le.c in the function le_load_fixup_record(). When processing malformed or circular LE fixup chains, relocation entries may be freed multiple times during error handling. A specially crafted LE binary can trigger heap corruption and cause the application to crash, resulting in a denial-of-service condition. An attacker with a crafted binary could cause a denial of service when the tool is integrated on a service pipeline.

Rizin is a UNIX-like reverse engineering framework and command-line toolset. Prior to 0.8.2, a heap overflow can be exploited when a malicious mach0 file, having bogus entries for the dyld chained segments, is parsed by rizin. This vulnerability is fixed in 0.8.2.

A vulnerability was found in rizinorg rizin up to 0.7.4. It has been rated as critical. This issue affects the function msf_stream_directory_free in the library /librz/bin/pdb/pdb.c. The manipulation of the argument -P leads to buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. Upgrading to version 0.8.0 is able to address this issue. It is recommended to upgrade the affected component.

rizin before v0.6.3 is vulnerable to Improper Neutralization of Special Elements via meta_set function in librz/analysis/meta.

rizin before v0.6.3 is vulnerable to Buffer Overflow via create_cache_bins, read_cache_accel, and rz_dyldcache_new_buf functions in librz/bin/format/mach0/dyldcache.c.

rizin before Release v0.6.3 is vulnerable to Uncontrolled Resource Consumption via bin_pe_parse_imports, Pe_r_bin_pe_parse_var, and estimate_slide.

Rizin is a UNIX-like reverse engineering framework and command-line toolset. Versions 0.6.0 and prior are vulnerable to integer overflow in `consume_count` of `src/gnu_v2/cplus-dem.c`. The overflow check is valid logic but, is missing the modulus if the block once compiled. The compiler sees this block as unreachable code since the prior statement is multiplication by 10 and fails to consider overflow assuming the count will always be a multiple of 10. Rizin version 0.6.1 contains a fix for the issue. A temporary workaround would be disabling C++ demangling using the configuration option `bin.demangle=false`.

An issue was discovered in function get_gnu_verneed in rizinorg Rizin prior to 0.5.0 verneed_entry allows attackers to cause a denial of service via crafted elf file.

A flaw was found in rizin. The create_section_from_phdr function allocates space for ELF section data by processing the headers. Crafted values in the headers can cause out of bounds reads, which can lead to memory corruption and possibly code execution through the binary object's callback function.

Rizin is a UNIX-like reverse engineering framework and command-line toolset. In version 0.5.1 and prior, converting a GDB registers profile file into a Rizin register profile can result in a stack-based buffer overflow when the `name`, `type`, or `groups` fields have longer values than expected. Users opening untrusted GDB registers files (e.g. with the `drpg` or `arpg` commands) are affected by this flaw. Commit d6196703d89c84467b600ba2692534579dc25ed4 contains a patch for this issue. As a workaround, review the GDB register profiles before loading them with `drpg`/`arpg` commands.

Rizin is a UNIX-like reverse engineering framework and command-line toolset. Versions 0.4.0 and prior are vulnerable to out-of-bounds write when parsing DEX files. A user opening a malicious DEX file could be affected by this vulnerability, allowing an attacker to execute code on the user's machine. A patch is available on the `dev` branch of the repository.

A vulnerability was found in rizin. The bug involves an ELF64 binary for the HPPA architecture. When a specially crafted binarygets analysed by rizin, it causes rizin to crash by freeing an uninitialized (and potentially user controlled, depending on the build) memory address.

Rizin v0.4.0 and below was discovered to contain an integer overflow via the function get_long_object(). This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted binary.

Rizin is a UNIX-like reverse engineering framework and command-line toolset. In versions up to and including 0.3.1 there is a heap-based out of bounds write in parse_die() when reversing an AMD64 ELF binary with DWARF debug info. When a malicious AMD64 ELF binary is opened by a victim user, Rizin may crash or execute unintended actions. No workaround are known and users are advised to upgrade.
