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.

Squid through 4.14 and 5.x through 5.0.5, in some configurations, allows information disclosure because of an out-of-bounds read in WCCP protocol data. This can be leveraged as part of a chain for remote code execution as nobody.
