Description
Integer overflow in the duplication operator in ActivePerl allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large multiplier, which may trigger a buffer overflow.
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.
