Vulnerabilities > CVE-2009-3037 - Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products
Buffer overflow in xlssr.dll in the Autonomy KeyView XLS viewer (aka File Viewer for Excel), as used in IBM Lotus Notes 5.x through 8.5.x, Symantec Mail Security, Symantec BrightMail Appliance, Symantec Data Loss Prevention (DLP), and other products, allows remote attackers to execute arbitrary code via a crafted .xls spreadsheet 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 Symantec Mail Security for SMTP running on the remote host is affected by an integer overflow condition when parsing a Shared String Table (SST) record inside of an Excel file. One of the fields in the SST is a 32-bit integer used to specify the size of a dynamic memory allocation. This integer is not validated, which can result in a heap-based buffer overflow condition. A remote attacker can exploit this by tricking a user into viewing an email with a specially crafted Excel file, resulting in the execution of arbitrary code as SYSTEM.|
