Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Okular contains a heap-based buffer overflow in the RLE decompression |
| 38 |

Impact |

====== |
| 43 |
|
| 44 |
A remote attacker could entice a user to open a specially crafted PBD |
| 45 |
file using Okular, possibly resulting in execution of arbitrary code |
| 46 |
with the privileges of the process, or a Denial of Service condition. |
| 47 |
|
| 48 |
Workaround |

Resolution |
| 54 |
========== |
| 55 |
|
