| 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 < 0.10.13-r1 >= 0.10.13-r1 |
| 33 | |
| 34 | Description |
| 35 | =========== |
| 36 | |
| 37 | There are numerous vulnerabilities in versions of Ethereal prior to |
| 38 | 0.10.13, including: |
| 39 | |
| 40 | * The SLIM3 and AgentX dissectors could overflow a buffer |
| 41 | (CVE-2005-3243). |
| 42 | |
| 43 | * iDEFENSE discovered a buffer overflow in the SRVLOC dissector |
| 44 | (CVE-2005-3184). |
| 45 | |
| 46 | * Multiple potential crashes in many dissectors have been fixed, see |
| 47 | References for further details. |
| 48 | |
| 49 | Furthermore an infinite loop was discovered in the IRC protocol |
| 50 | dissector of the 0.10.13 release (CVE-2005-3313). |
| 51 | |
| 52 | Impact |
| 53 | ====== |
| 54 | |
| 55 | An attacker might be able to use these vulnerabilities to crash |
| 56 | Ethereal or execute arbitrary code with the permissions of the user |
| 57 | running Ethereal, which could be the root user. |
| 58 | |
| 59 | Workaround |
| 60 | ========== |
| 61 | |
| 62 | There is no known workaround at this time. |
| 63 | |
| 64 | Resolution |
| 65 | ========== |
| 66 | |
| 67 | All Ethereal users should upgrade to the latest version: |
| 68 | |
| 69 | # emerge --sync |
| 70 | # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.13-r1" |
