| 15 | Synopsis |
| 16 | ======== |
| 17 | |
| 18 | Multiple vulnerabilities in libTIFF could lead to the execution of |
| 19 | arbitrary code or a Denial of Service. |
| 20 | |
| 21 | Background |
| 22 | ========== |
| 23 | |
| 24 | libTIFF provides support for reading and manipulating TIFF images. |
| 25 | |

| 34 | Description |
| 35 | =========== |
| 36 | |
| 37 | Multiple vulnerabilities, ranging from integer overflows and NULL |
| 38 | pointer dereferences to double frees, were reported in libTIFF. |
| 39 | |
| 40 | Impact |
| 41 | ====== |
| 42 | |
| 43 | An attacker could exploit these vulnerabilities by enticing a user to |
| 44 | open a specially crafted TIFF image, possibly leading to the execution |
| 45 | of arbitrary code or a Denial of Service. |
| 46 | |
| 47 | Workaround |
| 48 | ========== |
| 49 | |
| 50 | There is no known workaround at this time. |
| 51 | |
| 52 | Resolution |
| 53 | ========== |
| 54 | |
| 55 | All libTIFF users should upgrade to the latest version: |
| 56 | |
| 57 | # emerge --sync |
| 58 | # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.1" |
