Description
This security bulletin contains information about 1 security vulnerability.
1) Buffer overflow (CVE-ID: CVE-2012-3422)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
Remediation
Install update from vendor's website.
