Description Mark J. Cox 2007-04-18 10:09:35 UTC

In January 2007 a flaw was found affecting the SUN JRE; "Buffer overflow in Sun
JDK and Java Runtime Environment (JRE) 5.0 Update 9 and earlier, SDK and JRE
1.4.2_12 and earlier, and SDK and JRE 1.3.1_18 and earlier allows applets to
gain privileges via a GIF image with a block with a 0 width field, which
triggers memory corruption."

On 17th April 2007 IBM updated their alerts page to note that this issue
affected the IBM JRE and was fixed in 1.4.2 SR8

Also affects RHEL4Extras, RHEL3Extras

Comment 5 Mark J. Cox 2007-04-25 08:09:50 UTC

We're going to label this with impact=critical rather than important and we were
not able to prove this issue could not allow a malicious applet the ability to
run arbitrary code.  This issue was reported by IBM as affecting IBM Java on
20070417.
