CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------
PACKAGE : squid
SUMMARY : Multiple vulnerabilities
DATE : 2002-02-27 12:27:00
ID : CLA-2002:464
RELEVANT
RELEASES : 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0
- -------------------------------------------------------------------------
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.
