Vulnerability CVE-2012-3422
Published: 2012-08-07   Modified: 2012-08-08

Description:
The getFirstInTableInstance function in the IcedTea-Web plugin before 1.2.1 returns an uninitialized pointer when the instance_to_id_map hash is empty, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted web page, which causes an uninitialized memory location to be read.

Type:

CWE-119

 (Improper Restriction of Operations within the Bounds of a Memory Buffer)
