PACKAGE   : squid
SUMMARY   : Multiple vulnerabilities
DATE      : 2002-02-27 12:27:00

DESCRIPTION
 Squid is a high-performance proxy caching server.
 
 Three security issues[1] have recently been found in the Squid-2.X
 releases up to and including 2.4.STABLE3. From the Squid v2.4 patches
 page[2]:
 
 - Coredump on certain ftp:// style URL's[3]
 If certain constructed ftp:// style URL's are received then squid
 crashes, causing a denial of service (DoS) and maybe even remote
 execution of code.
 
 - SNMP memory leaks[4]
 The SNMP implementation in Squid had several memory leaks possibly
 causing a denial of service (DoS).
 
 - Failure to disable the HTCP port[5]
 "htcp_port 0" fails to completely disable the HTCP port as documented
 in squid.conf, instead HTCP will be listening on a random port
 number.
 
 Aditionally, the following patches from the site were applied:
 
 - Potential coredump on snmpwalk[6]
 Fixes a coredump on snmpwalk in certain configurations.
 
 - CONNECT/ssl core dump[7]
 Squid crashes on CONNECT requests that are allowed by http_access but
 denied by miss_access.
 
 - Filedescriptor leakage in the aufs store[8]
 Fixes a filedescriptor leakage in the "aufs" cache_dir store
 implementation.


SOLUTION
 It is recommended that all squid users upgrade to the latest 
 packages. This update will automatically restart the service if it is
 already running.
