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.

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.

CVE-2017-9465

 

 
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.

CVE-2017-9438

 

 
libyara/re.c in the regexp module in YARA 3.5.0 allows remote attackers to cause a denial of service (stack consumption) via a crafted rule (involving hex strings) that is mishandled in the _yr_re_emit function, a different vulnerability than CVE-2017-9304.

CVE-2017-9304

 

 
libyara/re.c in the regexp module in YARA 3.5.0 allows remote attackers to cause a denial of service (stack consumption) via a crafted rule that is mishandled in the _yr_re_emit function.

 
2017-05-14
 
CVE-2017-8929

 

 
The sized_string_cmp function in libyara/sizedstr.c in YARA 3.5.0 allows remote attackers to cause a denial of service (use-after-free and application crash) via a crafted rule.
