| 21 |
code or a Denial of Service. |
| 22 |
|
| 23 |
Background |
| 24 |

| 53 |
|
| 54 |
A remote attacker could exploit the integer overflow to execute |
| 55 |
arbitrary code or cause a Denial of Service. |
| 56 |
|
| 57 |
Workaround |
| 58 |
========== |
| 59 |

| 68 |
# emerge --ask --oneshot --verbose ">=net-im/gnugadu-2.2.6-r1" |
| 69 |
|
| 70 |
All Kadu users should upgrade to the latest version: |
| 71 |
|
| 72 |
# emerge --sync |
| 73 |
# emerge --ask --oneshot --verbose ">=net-im/kadu-0.4.1" |
| 74 |
|
| 75 |
All EKG users should upgrade to the latest version: |
| 76 |
|
| 77 |
# emerge --sync |
| 78 |
# emerge --ask --oneshot --verbose ">=net-im/ekg-1.6_rc3" |
| 79 |
|
| 80 |
All libgadu users should upgrade to the latest version: |
| 81 |
|
| 82 |
# emerge --sync |
| 83 |
# emerge --ask --oneshot --verbose ">=net-libs/libgadu-20050719" |

|
| 85 |
All CenterICQ users should upgrade to the latest version: |
| 86 |
|
| 87 |
