Multiple vulnerabilities in IBM Integrated Management Module II (IMM2) for System x, Flex and BladeCenter systems

1) NULL pointer dereference

EUVDB-ID: #VU77550

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-3194

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in crypto/rsa/rsa_ameth.c in OpenSSL. A remote attacker can trigger denial of service conditions via an RSA PSS ASN.1 signature that lacks a mask generation function parameter.

Mitigation

Install update from vendor's website.

2) Information disclosure

EUVDB-ID: #VU77552

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-3195

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists in the ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL. A remote attacker can gain unauthorized access to sensitive information from process memory by triggering a decoding failure in a PKCS#7 or CMS application.

Mitigation

Install update from vendor's website.

3) Race condition

EUVDB-ID: #VU77556

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-3196

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a race condition in the ssl/s3_clnt.c in OpenSSL when used for a multi-threaded client. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system via a crafted ServerKeyExchange message.

Mitigation

Install update from vendor's website.

4) Double free error

EUVDB-ID: #VU1622

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-0705

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists due to double-free error when parsing DSA private keys. A remote attacker can trigger memory corruption and cause the service to crash.

Mitigation

Install update from vendor's website.

5) Input validation error

EUVDB-ID: #VU32244

Risk: Medium

CVSSv3.1: 6.5 [AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-0797

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows remote attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (heap memory corruption or NULL pointer dereference) or possibly have unspecified other impact via a long digit string that is mishandled by the (1) BN_dec2bn or (2) BN_hex2bn function, related to crypto/bn/bn.h and crypto/bn/bn_print.c.

Mitigation

Install update from vendor's website.

6) Buffer overflow

EUVDB-ID: #VU82376

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-0799

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The 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.

Mitigation

Install update from vendor's website.
