15 | Synopsis |
16 | ======== |
17 | |
18 | libTIFF contains several vulnerabilities that could result in arbitrary |
19 | code execution. |
20 | |
21 | Background |
22 | ========== |
23 | |
24 | libTIFF provides support for reading and manipulating TIFF images. |
25 | |
26 | Affected packages |
27 | ================= |
28 | |
29 | ------------------------------------------------------------------- |
30 | Package / Vulnerable / Unaffected |
31 | ------------------------------------------------------------------- |
32 | 1 media-libs/tiff < 3.8.2-r2 >= 3.8.2-r2 |
33 | |
34 | Description |
35 | =========== |
36 | |
37 | Tavis Ormandy of the Google Security Team discovered several heap and |
38 | stack buffer overflows and other flaws in libTIFF. The affected parts |
39 | include the TIFFFetchShortPair(), TIFFScanLineSize() and |
40 | EstimateStripByteCounts() functions, and the PixarLog and NeXT RLE |
41 | decoders. |
42 | |
43 | Impact |
44 | ====== |
45 | |
46 | A remote attacker could entice a user to open a specially crafted TIFF |
47 | file, resulting in the possible execution of arbitrary code. |
48 | |
49 | Workaround |
50 | ========== |
51 | |
52 | There is no known workaround at this time. |
53 | |
54 | Resolution |
55 | ========== |
56 | |
57 | All libTIFF users should upgrade to the latest version: |
58 | |
59 | # emerge --sync |
60 | # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r2" |
