PARTIAL Summary
The iCalendar component in gwwww1.dll in GroupWise Internet Agent (GWIA) in Novell GroupWise 8.0 before Support Pack 3 allows remote attackers to cause a denial of service (out-of-bounds read and daemon crash) via a crafted date-time string in a .ics attachment.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| description | The version of Novell GroupWise Internet Agent running on the remote host is 8.x earlier than 8.0.3 or 12.x earlier than 12.0.1. It therefore is potentially affected by multiple vulnerabilities : - A denial of service vulnerability exists due to the way that the application parses date information within a received iCalendar message. A remote attacker could exploit this flaw to crash the affected service. (CVE-2011-3827) - An unspecified integer overflow vulnerability exists that could lead to code execution. (CVE-2012-0417) - An arbitrary file retrieval vulnerability exists due to a failure to properly filter certain crafted directory traversal sequences in the HTTP interface. (CVE-2012-0419) |
