Heap-based buffer overflow in the Remote Data Services (RDS) component of Microsoft Data Access Components (MDAC) 2.1 through 2.6, and Internet Explorer 5.01 through 6.0, allows remote attackers to execute code via a malformed HTTP request to the Data Stub.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (CPU consumption and memory leak) via a web page with a large number of images.

Microsoft Internet Explorer 4.0 through 6.0 could allow local users to differentiate between alphanumeric and non-alphanumeric characters used in a password by pressing certain control keys that jump between non-alphanumeric characters, which makes it easier to conduct a brute-force password guessing attack.

The Microsoft virtual machine (VM) in Internet Explorer 4.x and 5.x allows a remote attacker to read files via a malicious Java applet that escapes the Java sandbox, aka the "VM File Reading" vulnerability.

Vixie Cron on Linux systems allows local users to set parameters of sendmail commands via the MAILTO environmental variable.

Buffer overflow in Vixie cron allows local users to gain root access via a long MAILTO environment variable in a crontab file.
