15 Synopsis
16 ========
17
18 A vulnerability in CUPS might allow for the execution of arbitrary code
19 or a Denial of Service.
20
21 Background
22 ==========
23
24 CUPS provides a portable printing layer for UNIX-based operating
25 systems.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------

35 Description
36 ===========
37
38 Thomas Pollet reported a possible integer overflow vulnerability in the
39 PNG image handling in the file filter/image-png.c.
40
41 Impact
42 ======
43
44 A malicious user might be able to execute arbitrary code with the
45 privileges of the user running CUPS (usually lp), or cause a Denial of
46 Service by sending a specially crafted PNG image to the print server.
47 The vulnerability is exploitable via the network if CUPS is sharing
48 printers remotely.
49
50 Workaround
51 ==========
52
53 There is no known workaround at this time.
54
55 Resolution
56 ==========
57
58 All CUPS users should upgrade to the latest version:
59
60 # emerge --sync
61 # emerge --ask --oneshot --verbose ">=net-print/cups-1.2.12-r8"
