Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU82376
Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2016-0799
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to fmtstr function in crypto/bio/b_print.c in OpenSSL improperly calculates string lengths. A remote attacker can cause a denial of service (overflow and out-of-bounds read) or possibly have unspecified other impact via a long string.

2) Heap overflow
EUVDB-ID: #VU640
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2016-2105
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote user to cause heap overflow on the target system.
The weakness is caused by insufficient input validation. By sending a great deal of input data attackers are able to cause overflow of the EVP_EncodeUpdate() function used for binary data encoding.
Successful exploitation of the vulnerability may result in heap overflow on the vulnerable system.

3) Input validation error
EUVDB-ID: #VU33809
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2016-2106
CWE-ID:
CWE-20 - Improper input validation

5) Memory corruption
EUVDB-ID: #VU638
Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2016-2108
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote user to cause memory corruption on the target system.
The weakness exists due to buffer underflow with an out-of-bounds write in i2c_ASN1_INTEGER. As ASN.1 parser (specifically, d2i_ASN1_TYPE) can misinterpret a large universal tag as a negative zero value, attacker may easily corrupt memory.
Successful exploitation of the vulnerability will allow a malicious user to trigger memory corruption on the vulnerable system.

6) Excessive memory allocation
EUVDB-ID: #VU641
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2016-2109
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote user to cause excessive memory allocation on the target system.
The weakness exists during reading ASN.1 data by d2i_CMS_bio() function. A short invalid encoding leads to distribution of large amounts of memory for excessive resources or exhausting memory.
Successful exploitation of the vulnerability may result in excessive memory allocation.

7) Buffer overflow
EUVDB-ID: #VU89734
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2016-2842
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to a doapr_outch function in crypto/bio/b_print.c in OpenSSL does not verify that a certain memory allocation succeeds. A remote attacker can cause a denial of service (out-of-bounds write or memory consumption) or possibly have unspecified other impact via a long string
