| 15 | Synopsis |
| 16 | ======== |
| 17 | |
| 18 | Ethereal is vulnerable to numerous vulnerabilities potentially |
| 19 | resulting in the execution of arbitrary code or abnormal termination. |
| 20 | |
| 21 | Background |
| 22 | ========== |
| 23 | |
| 24 | Ethereal is a feature-rich network protocol analyzer. |
| 25 | |
| 26 | Affected packages |
| 27 | ================= |
| 28 | |
| 29 | ------------------------------------------------------------------- |
| 30 | Package / Vulnerable / Unaffected |
| 31 | ------------------------------------------------------------------- |
| 32 | 1 net-analyzer/ethereal < 0.10.12 >= 0.10.12 |
| 33 | |
| 34 | Description |
| 35 | =========== |
| 36 | |
| 37 | There are numerous vulnerabilities in versions of Ethereal prior to |
| 38 | 0.10.12, including: |
| 39 | |
| 40 | * The SMB dissector could overflow a buffer or exhaust memory |
| 41 | (CAN-2005-2365). |
| 42 | |
| 43 | * iDEFENSE discovered that several dissectors are vulnerable to |
| 44 | format string overflows (CAN-2005-2367). |
| 45 | |
| 46 | * Additionally multiple potential crashes in many dissectors have |
| 47 | been fixed, see References for further details. |
| 48 | |
| 49 | Impact |
| 50 | ====== |
| 51 | |
| 52 | An attacker might be able to use these vulnerabilities to crash |
| 53 | Ethereal or execute arbitrary code with the permissions of the user |
| 54 | running Ethereal, which could be the root user. |
| 55 | |
| 56 | Workaround |
| 57 | ========== |
| 58 | |
| 59 | There is no known workaround at this time. |
| 60 | |
| 61 | Resolution |
| 62 | ========== |
| 63 | |
| 64 | All Ethereal users should upgrade to the latest version: |
| 65 | |
| 66 | # emerge --sync |
| 67 | # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.12" |
