Vulnerability Details

CVEID: CVE-2016-8610**
DESCRIPTION:** The SSL/TLS protocol is vulnerable to a denial of service, caused by an error when processing ALERT packets during a SSL handshake. By sending specially-crafted plain-text ALERT packets, a remote attacker could exploit this vulnerability to consume all available CPU resources. Note: This vulnerability is called “SSL-Death-Alert”.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/118296 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:H)

CVEID: CVE-2017-3731**
DESCRIPTION:** OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read when using a specific cipher. By sending specially crafted truncated packets, a remote attacker could exploit this vulnerability using CHACHA20/POLY1305 to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/121312 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2015-8325**
DESCRIPTION:** OpenSSH could allow a local attacker to gain elevated privileges on the system, caused by an error in the do_setup_env function when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories. By using an LD_PRELOAD environment variable, an attacker could exploit this vulnerability to gain elevated privileges on the system.
