Content

VULNERABILITY DETAILS ** ** CVE ID: CVE-2013-1571 **DESCRIPTION: **
The Javadoc documentation generated for the Sterling External Authentication Server has HTML with embedded Javascript that contains a security vulnerability.
CVSS Base Score: 4.3 **CVSS Temporal Score:**See https://exchange.xforce.ibmcloud.com/vulnerabilities/84715 *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE ID: CVE-2013-1500 **DESCRIPTION: **
Some native internal implementation code in the AWT component of the JRE creates a shared memory segment with world read/write permissions. This allows potentially sensitive data to be accessed and modified by a local user.
CVSS Base Score: 3.6 **CVSS Temporal Score: **See https://exchange.xforce.ibmcloud.com/vulnerabilities/85062 *CVSS Environmental Score:**Undefined CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:P/A:N)

CVE ID: CVE-2013-0443 **DESCRIPTION: **
A vulnerability in Java Runtime Environment allows remote attackers to affect confidentiality and integrity via vectors related to JSSE.
CVSS Base Score: 4 **CVSS Temporal Score:**See https://exchange.xforce.ibmcloud.com/vulnerabilities/81801_ _ *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N)

CVE ID: CVE-2013-0440 **DESCRIPTION: **
A vulnerability in Java Runtime Environment allows remote attackers to affect availability via vectors related to JSSE.
CVSS Base Score: 5 **CVSS Temporal Score: **See https://exchange.xforce.ibmcloud.com/vulnerabilities/81799 *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE ID: CVE-2013-0169 **DESCRIPTION: **
The TLS protocol does not properly consider timing side-channel attacks, which allows remote attackers to conduct distinguishing attacks and plain-text recovery attacks via statistical analysis of timing data for crafted packets, aka the “Lucky Thirteen” issue.
CVSS Base Score: 4.3 **CVSS Temporal Score:**See https://exchange.xforce.ibmcloud.com/vulnerabilities/81902 *CVSS Environmental Score:**Undefined CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N)
