Vulnerabilities > CVE-2015-8836 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Attack vector
LOCAL Attack complexity
LOW Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
Integer overflow in the isofs_real_read_zf function in isofs.c in FuseISO 20070708 might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a large ZF block size in an ISO file, leading to a heap-based buffer overflow.

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 | It was discovered that fuseiso, a user-space implementation of the ISO 9660 file system based on FUSE, contains several vulnerabilities. - CVE-2015-8836 A stack-based buffer overflow may allow attackers who can trick a user into mounting a crafted ISO 9660 file system to cause a denial of service (crash), or, potentially, execute arbitrary code. - CVE-2015-8837 An integer overflow leads to a heap-based buffer overflow, which allows an attacker (who can trick a user into mounting a crafted ISO 9660 file system) to cause a denial of service (crash), or, potentially, execute arbitrary code. |
