| Descripción: | Summary:
The remote host is missing an update for the 'java-1.7.0-openjdk' package(s) announced via the ALAS-2016-643 advisory.
Vulnerability Insight:
An out-of-bounds write flaw was found in the JPEG image format decoder in the AWT component in OpenJDK. A specially crafted JPEG image could cause a Java application to crash or, possibly execute arbitrary code. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions. (CVE-2016-0483)
An integer signedness issue was found in the font parsing code in the 2D component in OpenJDK. A specially crafted font file could possibly cause the Java Virtual Machine to execute arbitrary code, allowing an untrusted Java application or applet to bypass Java sandbox restrictions. (CVE-2016-0494)
It was discovered that the JAXP component in OpenJDK did not properly enforce the totalEntitySizeLimit limit. An attacker able to make a Java application process a specially crafted XML file could use this flaw to make the application consume an excessive amount of memory. (CVE-2016-0466)
A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client. (CVE-2015-7575)
Multiple flaws were discovered in the Libraries, Networking, and JMX components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2015-4871, CVE-2016-0402, CVE-2016-0448)
Note: This update also disallows the use of the MD5 hash algorithm in the certification path processing. The use of MD5 can be re-enabled by removing MD5 from the jdk.certpath.disabledAlgorithms security property defined in the java.security file.
