Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
libextractor is vulnerable to two heap overflow vulnerabilities which |
| 19 |
could lead to the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
libextractor is a library used to extract metadata from arbitrary |
| 25 |
files. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-libs/libextractor < 0.5.14 >= 0.5.14 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Luigi Auriemma has found two heap-based buffer overflows in |
| 39 |
libextractor 0.5.13 and earlier: one of them occurs in the |
| 40 |
asf_read_header function in the ASF plugin, and the other occurs in the |
| 41 |
parse_trak_atom function in the Qt plugin. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
By enticing a user to open a malformed file using an application that |
| 47 |
employs libextractor and its ASF or Qt plugins, an attacker could |
| 48 |
execute arbitrary code in the context of the application running the |
| 49 |
affected library. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All libextractor users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=media-libs/libextractor-0.5.14" |
| 63 |
