15 | Synopsis |
16 | ======== |
17 | |
18 | Multiple vulnerabilities have been found in libTIFF, allowing remote |
19 | attackers to execute arbitrary code or cause Denial of Service. |
20 | |
21 | Background |
22 | ========== |
23 | |
24 | libTIFF provides support for reading and manipulating TIFF (Tagged |
25 | Image File Format) images. |
26 | |
27 | Affected packages |
28 | ================= |
29 | |
30 | ------------------------------------------------------------------- |

36 | Description |
37 | =========== |
38 | |
39 | Multiple vulnerabilities have been discovered in libTIFF. Please review |
40 | the CVE identifiers referenced below for details. |
41 | |
42 | Impact |
43 | ====== |
44 | |
45 | A remote attacker could entice a user to open a specially crafted TIFF |
46 | file with an application making use of libTIFF, possibly resulting in |
47 | execution of arbitrary code with the privileges of the user running the |
48 | application or a Denial of Service condition. |
49 | |
50 | Workaround |
51 | ========== |
52 | |
53 | There is no known workaround at this time. |
54 | |
55 | Resolution |
56 | ========== |
57 | |
58 | All libTIFF 4.* users should upgrade to the latest version: |
59 | |
60 | # emerge --sync |
61 | # emerge --ask --oneshot --verbose ">=media-libs/tiff-4.0.3-r6" |
62 | |
63 | All libTIFF 3.* users should upgrade to the latest version: |
64 | |
65 | # emerge --sync |
66 | # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.9.7-r1" |
67 | |
68 | Packages which depend on this library may need to be recompiled. Tools |
69 | such as revdep-rebuild may assist in identifying these packages. |
