Vulnerability details

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application when processing ESI response content. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that Squid is acting as reverse proxy where ESI feature has been enabled at build time.
