NVD Description
Note: Versions mentioned in the description apply only to the upstream squid:4/libecap package and not the squid:4/libecap package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:8 relevant fixed versions and status.
An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow.
