Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability in Xpdf might allow local attackers to execute |
| 19 |
arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Xpdf is a PDF file viewer that runs under the X Window System. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |

------------------------------------------------------------------- |

Package / Vulnerable / Unaffected |
| 31 |

| 32 |
1 app-text/xpdf < 3.02-r2 >= 3.02-r2 |

|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Erik Wallin reported that Gentoo's Xpdf attempts to read the "xpdfrc" |
| 38 |
file from the current working directory if it cannot find a ".xpdfrc" |
| 39 |
file in the user's home directory. This is caused by a missing |
| 40 |
definition of the SYSTEM_XPDFRC macro when compiling a repackaged |
| 41 |
version of Xpdf. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A local attacker could entice a user to run "xpdf" from a directory |
| 47 |
containing a specially crafted "xpdfrc" file, resulting in the |
| 48 |
execution of arbitrary code when attempting to, e.g., print a file. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
Do not run Xpdf from untrusted working directories. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Xpdf users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.02-r2" |
| 62 |
|
