script_tag(name:"insight", value:"Squid is a high-performance proxy caching server for web clients that
supports FTP, Gopher, and HTTP data objects.
A denial of service flaw was found in the way the Squid Cache Manager
processed certain requests. A remote attacker who is able to access the
Cache Manager CGI could use this flaw to cause Squid to consume an
excessive amount of memory. (CVE-2012-5643)
This update also fixes the following bugs:
* Due to a bug in the ConnStateData::noteMoreBodySpaceAvailable() function,
child processes of Squid terminated upon encountering a failed assertion.
An upstream patch has been provided and Squid child processes no longer
terminate. (BZ#805879)
* Due to an upstream patch, which renamed the HTTP header controlling
persistent connections from 'Proxy-Connection' to 'Connection', the NTLM
pass-through authentication does not work, thus preventing login. This
update adds the new 'http10' option to the squid.conf file, which can be
used to enable the change in the patch. This option is set to 'off' by
default. When set to 'on', the NTLM pass-through authentication works
properly, thus allowing login attempts to succeed. (BZ#844723)
* When the IPv6 protocol was disabled and Squid tried to handle an HTTP GET
request containing an IPv6 address, the Squid child process terminated due
to signal 6. This bug has been fixed and such requests are now handled as
expected. (BZ#832484)
* The old 'stale if hit' logic did not account for cases where the stored
stale response became fresh due to a successful re-validation with the
origin server. Consequently, incorrect warning messages were returned. Now,
Squid no longer marks elements as stale in the described scenario.
(BZ#847056)
* When squid packages were installed before samba-winbind, the wbpriv group
did not include Squid. Consequently, NTLM authentication calls failed. Now,
Squid correctly adds itself into the wbpriv group if samba-winbind is
installed before Squid, thus fixing this bug. (BZ#797571)
* In FIPS mode, Squid was using private MD5 hash functions for user
authentication and network access. As MD5 is incompatible with FIPS mode,
Squid could fail to start. This update limits the use of the private MD5
functions to local disk file hash identifiers, thus allowing Squid to work
in FIPS mode. (BZ#833086)
* Under high system load, the squid process could terminate unexpectedly
with a segmentation fault during reboot. This update provides better memory
handling during reboot, thus fixing this ...
