Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
An error in OpenSSL might allow for a Denial of Service when printing |
| 19 |
certificate details. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer |
| 25 |
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general |
| 26 |
purpose cryptography library. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 dev-libs/openssl < 0.9.8k >= 0.9.8k |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
The ASN1_STRING_print_ex() function does not properly check the |
| 40 |
provided length of a BMPString or UniversalString, leading to an |
| 41 |
invalid memory access. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could entice a user or automated system to print a |
| 47 |
specially crafted certificate, possibly leading to a Denial of Service. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All OpenSSL users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8k" |
| 61 |
|
| 62 |
