Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2021-03-10 02:55:32 UTC 
CVE-2021-28116:

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.


Not much information available but this CVE itself only appears to be
information disclosure, and apparently no public fix yet.
Comment 1 Mikle Kolyada (RETIRED) archtester Gentoo Infrastructure gentoo-dev Security 2021-05-17 08:06:16 UTC 
4.15 is in stable now.
