Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Multiple vulnerabilities have been discovered in Mono and Mono |
| 41 |
debugger. Please review the CVE identifiers referenced below for |
| 42 |
details. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A remote attacker could execute arbitrary code, bypass general |
| 48 |
constraints, obtain the source code for .aspx applications, obtain |
| 49 |
other sensitive information, cause a Denial of Service, modify internal |
| 50 |
data structures, or corrupt the internal state of the security manager. |
| 51 |
|
| 52 |
A local attacker could entice a user into running Mono debugger in a |
| 53 |
directory containing a specially crafted library file to execute |
| 54 |
arbitrary code with the privileges of the user running Mono debugger. |
| 55 |
|
| 56 |
A context-dependant attacker could bypass the authentication mechanism |
| 57 |
provided by the XML Signature specification. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
There is no known workaround at this time. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
All Mono debugger users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot -v ">=dev-util/mono-debugger-2.8.1-r1" |
| 71 |
|
| 72 |
All Mono users should upgrade to the latest version: |
| 73 |
|
| 74 |
# emerge --sync |
| 75 |
# emerge --ask --oneshot --verbose ">=dev-lang/mono-2.10.2-r1" |
| 76 |
