15 Synopsis
16 ========
17
18 Squid contains several bugs when handling certain malformed requests
19 resulting in a Denial of Service.
20
21 Background
22 ==========
23
24 Squid is a full-featured Web proxy cache designed to run on Unix-like
25 systems. It supports proxying and caching of HTTP, FTP, and other
26 protocols, as well as SSL support, cache hierarchies, transparent
27 caching, access control lists and many more features.
28
29 Affected packages
30 =================
31
32 -------------------------------------------------------------------
33 Package / Vulnerable / Unaffected
34 -------------------------------------------------------------------
35 1 www-proxy/squid < 2.5.10-r2 >= 2.5.10-r2
36
37 Description
38 ===========
39
40 Certain malformed requests result in a segmentation fault in the
41 sslConnectTimeout function, handling of other certain requests trigger
42 assertion failures.
43
44 Impact
45 ======
46
47 By performing malformed requests an attacker could cause Squid to crash
48 by triggering an assertion failure or invalid memory reference.
49
50 Workaround
51 ==========
52
53 There is no known workaround at this time.
54
55 Resolution
56 ==========
57
58 All Squid users should upgrade to the latest version:
59
60 # emerge --sync
61 # emerge --ask --oneshot --verbose ">=www-proxy/squid-2.5.10-r2"
