Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2015-3194)

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.


2) Information disclosure (CVE-ID: CVE-2015-3195)

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.


3) Race condition (CVE-ID: CVE-2015-3196)

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.


4) Double free error (CVE-ID: CVE-2016-0705)

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.

5) Input validation error (CVE-ID: CVE-2016-0797)

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.


6) Buffer overflow (CVE-ID: CVE-2016-0799)

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.
