38 | Description |
39 | =========== |
40 | |
41 | Multiple vulnerabilities have been discovered in libexif and exif. |
42 | Please review the CVE identifiers referenced below for details. |
43 | |
44 | Impact |
45 | ====== |
46 | |
47 | A remote attacker could entice a user to open a specially crafted image |
48 | file using exif or an application linked against libexif, possibly |
49 | resulting in execution of arbitrary code with the privileges of the |
50 | process or a Denial of Service condition. |
51 | |
52 | Workaround |
53 | ========== |
54 | |
55 | There is no known workaround at this time. |
56 | |
57 | Resolution |
58 | ========== |
59 | |
60 | All libexif users should upgrade to the latest version: |
61 | |
62 | # emerge --sync |
63 | # emerge --ask --oneshot --verbose ">=media-libs/libexif-0.6.21" |
64 | |
65 | Packages which depend on this library may need to be recompiled. Tools |
66 | such as revdep-rebuild may assist in identifying some of these |
67 | packages. |
68 | |
69 | All exif users should upgrade to the latest version: |
70 | |
71 | # emerge --sync |
72 | # emerge --ask --oneshot --verbose ">=media-gfx/exif-0.6.21" |
