Vulnerability Details

CVE-ID: CVE-2015-3194 **
Description:OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when verifying certificates via a malformed routine. An attacker could exploit this vulnerability using signature verification routines with an absent PSS parameter to cause any certificate verification operation to crash. **
CVSS Base Score:
5.3**
CVSS Temporal Score:** See https://exchange.xforce.ibmcloud.com/vulnerabilities/108503 for the current score**
CVSS Environmental Score:** Undefined*
CVSS Vector:** CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L

**
CVE-ID:CVE-2015-3195 **
Description:OpenSSL could allow a remote attacker to obtain sensitive information, caused by a memory leak in a malformed X509_ATTRIBUTE structure. An attacker could exploit this vulnerability to obtain CMS data and other sensitive information. **
CVSS Base Score:
5.3

CVSS Temporal Score:** See https://exchange.xforce.ibmcloud.com/vulnerabilities/108504 for the current score**
CVSS Environmental Score:** Undefined*
CVSS Vector:** CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N

**
CVE-ID:CVE-2015-3196 **
Description:OpenSSL is vulnerable to a denial of service, caused by a race condition when PSK identity hints are received by a multi-threaded client and the SSL_CTX structure is updated with the incorrect value. An attacker could exploit this vulnerability to possibly corrupt memory and cause a denial of service. **
CVSS Base Score:
3.7

CVSS Temporal Score:** See https://exchange.xforce.ibmcloud.com/vulnerabilities/108505 for the current score**
CVSS Environmental Score:** Undefined*
