Arch Linux Security Advisory ASA-201504-15 ========================================== Severity: Critical Date : 2015-04-17 CVE-ID : CVE-2005-1080 CVE-2015-0460 CVE-2015-0469 CVE-2015-0477 CVE-2015-0478 CVE-2015-0480 CVE-2015-0488 Package : jdk7-openjdk Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package jdk7-openjdk before version 7.u79_2.5.5-1 is vulnerable to multiple issues including but not limited to arbitrary code execution, directory traversal, sandbox restriction bypass and denial of service. Resolution ========== Upgrade to 7.u79_2.5.5-1. # pacman -Syu "jdk7-openjdk>=7.u79_2.5.5-1" The problems have been fixed upstream in version 7.u79_2.5.5. Workaround ========== None. Description =========== - CVE-2005-1080 CVE-2015-0480 (directory traversal) A directory traversal flaw was found in the way the jar tool extracted JAR archive files. A specially crafted JAR archive could cause jar to overwrite arbitrary files writable by the user running jar when the archive was extracted. - CVE-2015-0460 (arbitrary code execution) A flaw was found in the way the Hotspot component in OpenJDK handled phantom references. An untrusted Java application or applet could use this flaw to corrupt the Java Virtual Machine memory and, possibly, execute arbitrary code, bypassing Java sandbox restrictions. - CVE-2015-0469 (arbitrary code execution) An off-by-one flaw, leading to a buffer overflow, 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-2015-0477 (sandbox restriction bypass) A flaw was discovered in the Beans component in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. - CVE-2015-0478 (weak implementation) It was found that the RSA implementation in the JCE component in OpenJDK did not follow recommended practices for implementing RSA signatures. - CVE-2015-0488 (denial of service) A flaw was found in the way the JSSE component in OpenJDK parsed X.509 certificate options. A specially crafted certificate could cause JSSE to raise an exception, possibly causing an application using JSSE to exit unexpectedly. Impact ====== A remote attacker is able to execute arbitrary code, perform directory traversal, bypass certain sandbox restrictions or perform a denial of service attack via various vectors.
