Vulnerabilities > CVE-2015-7049 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Apple Xcode
Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
otools in Apple Xcode before 7.2 allows local users to gain privileges or cause a denial of service (memory corruption) via a crafted mach-o file, a different vulnerability than CVE-2015-7057.
Vulnerable Configurations
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 Apple Xcode installed on the remote Mac OS X host is prior to 7.2. It is, therefore, affected by multiple vulnerabilities : - Multiple remote code execution vulnerabilities exist due to a flaw in the otools component that is triggered when handling Mach-O files. A remote attacker can exploit these vulnerabilities to execute arbitrary code. (CVE-2015-7049, CVE-2015-7057) - A flaw exists in the IDE SCM due to the .gitignore directive not being honored. An unauthenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2015-7056) - A remote code execution vulnerability exists due to a flaw in git-remote-ext that is triggered when handling a specially crafted URL. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2015-7082) |
