| Package | Affected versions | Patched versions |
|---|---|---|
| icedtea-web | = 1.0= 1.1≤ 1.2 |
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.
