NVD Description
Note: Versions mentioned in the description apply only to the upstream libecap package and not the libecap package as distributed by RHEL.
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.
