CVE-2021-45429

CWE-120
 
 
A Buffer Overflow vulnerablity exists in VirusTotal YARA git commit: 605b2edf07ed8eb9a2c61ba22eb2e7c362f47ba7 via yr_set_configuration in yara/libyara/libyara.c, which could cause a Denial of Service.

CVE-2019-19648

CWE-125
 
 
In the macho_parse_file functionality in macho/macho.c of YARA 3.11.0, command_size may be inconsistent with the real size. A specially crafted MachO file can cause an out-of-bounds memory access, resulting in Denial of Service (application crash) or potential code execution.

CVE-2019-5020

CWE-20
 
 
An exploitable denial of service vulnerability exists in the object lookup functionality of Yara 3.8.1. A specially crafted binary file can cause a negative value to be read to satisfy an assert, resulting in Denial of Service. An attacker can create a malicious binary to trigger this vulnerability.

CVE-2018-19976

CWE-200
 
 
In YARA 3.8.1, bytecode in a specially crafted compiled rule is exposed to information about its environment, in libyara/exec.c. This is a consequence of the design of the YARA virtual machine.

 
 
CVE-2018-19975

CWE-125
 
 
In YARA 3.8.1, bytecode in a specially crafted compiled rule can read data from any arbitrary address in memory, in libyara/exec.c. Specifically, OP_COUNT can read a DWORD.

 
 
CVE-2018-19974

CWE-200
 
 
In YARA 3.8.1, bytecode in a specially crafted compiled rule can read uninitialized data from VM scratch memory in libyara/exec.c. This can allow attackers to discover addresses in the real stack (not the YARA virtual stack).

CVE-2018-12035

CWE-787
 
 
In YARA 3.7.1 and prior, parsing a specially crafted compiled rule file can cause an out of bounds write vulnerability in yr_execute_code in libyara/exec.c.

 
 
CVE-2018-12034

CWE-125
 
 
In YARA 3.7.1 and prior, parsing a specially crafted compiled rule file can cause an out of bounds read vulnerability in yr_execute_code in libyara/exec.c.

 
2017-07-17
 
CVE-2017-11328

 
 
Heap buffer overflow in the yr_object_array_set_item() function in object.c in YARA 3.x allows a denial-of-service attack by scanning a crafted .NET file.

 
2017-06-06
 
CVE-2017-9465

CWE-125
 
 
The yr_arena_write_data function in YARA 3.6.1 allows remote attackers to cause a denial of service (buffer over-read and application crash) or obtain sensitive information from process memory via a crafted file that is mishandled in the yr_re_fast_exec function in libyara/re.c and the _yr_scan_match_callback function in libyara/scan.c.
