Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities were found in glibc, the worst of which |
| 19 |
allowing local attackers to execute arbitrary code as root. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The GNU C library is the standard C library used by Gentoo Linux |
| 25 |
systems. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities were found in glibc, amongst others the |
| 39 |
widely-known recent LD_AUDIT and $ORIGIN issues. For further |
| 40 |
information please consult the CVE entries referenced below. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A local attacker could execute arbitrary code as root, cause a Denial |
| 46 |
of Service, or gain privileges. Additionally, a user-assisted remote |
| 47 |
attacker could cause the execution of arbitrary code, and a |
| 48 |
context-dependent attacker could cause a Denial of Service. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All GNU C library users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=sys-libs/glibc-2.11.2-r3" |
| 62 |
