Description Josh Bressers 2005-02-01 16:58:08 UTC
If a proxy_auth acl is incorrectly defined with no members then any http_access
rules using this acl will give unpredictable results depending on the results of
earlier acl lookups. This patch corrects both the reason to why acl lookups
became unpredictable and makes Squid reject such incorrect acl definitions.

The upstream patch for this issue is here:
http://www.squid-cache.org/Versions/v2/2.5/bugs/squid-2.5.STABLE4-empty_proxy_auth.patch

Comment 1 Josh Bressers 2005-02-01 16:59:48 UTC
This issue should also affect RHEL2.1

Comment 2 Jay Fenlason 2005-02-01 19:58:16 UTC
RHEL-2.1 is safe--squid-2.4.STABLE7 errors on startup if the config file 
contains empty proxy_auth acls. 

Comment 3 David Eisenstein 2005-10-15 15:47:41 UTC
In which of the RHSA's was this issue fixed?

Comment 4 David Eisenstein 2005-10-15 15:50:52 UTC
D'oh.  I think I found it -- RHSA-2005:061.  Sorry to bother you.
