| 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" |
