Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities have been discovered in teTeX, allowing for |
19 |
user-assisted execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
teTeX is a complete TeX distribution for editing documents. |
25 |
|
26 |
Affected packages |
27 |
================= |
28 |
|

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

Package / Vulnerable / Unaffected |

------------------------------------------------------------------- |
32 |
1 app-text/tetex < 3.0_p1-r4 >= 3.0_p1-r4 |

|
34 |
Description |
35 |
=========== |
36 |
|
37 |
Mark Richters discovered a buffer overflow in the open_sty() function |
38 |
in file mkind.c. Other vulnerabilities have also been discovered in the |
39 |
same file but might not be exploitable (CVE-2007-0650). Tetex also |
40 |
includes vulnerable code from GD library (GLSA 200708-05), and from |
41 |
Xpdf (CVE-2007-3387). |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A remote attacker could entice a user to process a specially crafted |
47 |
PNG, GIF or PDF file, or to execute "makeindex" on an overly long |
48 |
filename. In both cases, this could lead to the remote execution of |
49 |
arbitrary code with the privileges of the user running the application. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All teTeX users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=app-text/tetex-3.0_p1-r4" |
63 |
