Description
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.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
