Vulnerability Details

CVEID: 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)
**
CVEID:** 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
