[原文]ActivePerl 5.8.x and others, and Larry Wall's Perl 5.6.1 and others, when running on Windows systems, allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long argument to the system command, which leads to a stack-based buffer overflow. NOTE: it is unclear whether this bug is in Perl or the OS API that is used by Perl.

ActivePerl 5.x,Cygwin 1.5.x System Function Call Buffer Overflow Vulnerability (EDBID:24128)

N/A [点击下载]

ActiveState Perl and Perl for cygwin are both reported to be prone to a buffer overflow vulnerability. 

The issue is reported to exist due to a lack of sufficient bounds checking that is performed on data that is passed to a Perl system() function call. This vulnerability may permit an attacker to influence execution flow of a vulnerable Perl script to ultimately execute arbitrary code. Arbitrary code execution will occur in the context of the user who is running the malicious Perl script.

Local Access Required Denial of Service, Input Manipulation
Loss of Availability
Exploit Public

- 漏洞描述

A local overflow exists in ActivePerl for Win32. The interpreter fails to do proper bounds checking on input to the system()function resulting in a buffer overflow. With a specially crafted request, an attacker can cause an interpreter crash resulting in a loss of availability. It may be possible to manipulate the input so as to cause execution of arbitrary code resulting in a loss of confidentiality.
