National Cyber Awareness System
Vulnerability Summary for CVE-2006-1542
Original release date:03/30/2006
Stack-based buffer overflow in Python 2.4.2 and earlier, running on Linux 184.108.40.206 under gcc 4.0.3 with libc 2.3.5, allows local users to cause a "stack overflow," and possibly gain privileges, by running a script from a current working directory that has a long name, related to the realpath function. NOTE: this might not be a vulnerability. However, the fact that it appears in a programming language interpreter could mean that some applications are affected, although attack scenarios might be limited because the attacker might already need to cross privilege boundaries to cause an exploitable program to be placed in a directory with a long name; or, depending on the method that Python uses to determine the current working directory, setuid applications might be affected.
CVSS Severity (version 2.0 upgrade from v1.0):
CVSS Version 2 Metrics:
Access Vector: Locally exploitable
Access Complexity: High
Authentication: Not required to exploit
Impact Type:Provides unauthorized access, Allows partial confidentiality, integrity, and availability violation; Allows unauthorized disclosure of information; Allows disruption of service
Successful exploitation requires that the Python is running on Linux 220.127.116.11 under gcc 4.0.3 with libc 2.3.5}
