Two vulnerabilities open to remote exploitation by hackers have been
found in Java Development Kit, one of which could be used to take over a
JDK (Java Development Kit) is a software development tool made by Sun
Microsystems specifically for Java users. The vulnerabilities were rated
"critical" by FrSIRT (French Security Incident Response Team), a
security research organization based in France.
One flaw is caused by an integer overflow error in the image parser when
processing ICC profiles embedded within JPEG images, according to FrSIRT
Security experts at Secunia outlined the dangers of the flaw in a
separate advisory. "This can be exploited to crash the JVM and
potentially allow the execution of arbitrary code by e.g. tricking an
application using the JDK to process a malicious image file," Secunia
security experts stated.
The second vulnerability is caused by an error in the BMP image parser
when processing malformed files on Unix/Linux systems, which could be
exploited by attackers to cause a denial of service. Both flaws affect
Sun JDK version 1.x.
Users can find an answer to both vulnerabilities by upgrading to JDK
versions 1.5.0_11-b03 or 1.6.0_01-b06.
