CVE-2012-3422: Red Hat Icedtea-Web

Medium severity, CVSS 6.8. EPSS: 3.1% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Icedtea-Web: up to and including 1.2; version 1.0 only; version 1.1 only
