Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
libextractor is affected by several overflow vulnerabilities in the |
| 19 |
PDF, Real and PNG extractors, making it vulnerable to execution of |
| 20 |
arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
libextractor is a library used to extract meta-data from files. It |
| 26 |
makes use of Xpdf code to extract information from PDF files. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |

|

------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 media-libs/libextractor < 0.5.0 >= 0.5.0 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Xpdf is vulnerable to multiple overflows, as described in GLSA |
| 40 |
200501-28. Also, integer overflows were discovered in Real and PNG |
| 41 |
extractors. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
An attacker could design malicious PDF, PNG or Real files which, when |
| 47 |
processed by an application making use of libextractor, would result in |
| 48 |
the execution of arbitrary code with the rights of the user running the |
| 49 |
application. |
| 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-0.5.0" |
| 63 |
|
