18 | Synopsis |
19 | ======== |
20 | |
21 | Multiple vulnerabilities were discovered in PTeX, possibly allowing the |
22 | execution of arbitrary code or overwriting arbitrary files. |
23 | |
24 | Background |
25 | ========== |
26 | |
27 | PTeX is a TeX distribution with Japanese support. It is used for |
28 | creating and manipulating LaTeX documents. |
29 | |
30 | Affected packages |
31 | ================= |
32 | |
33 | ------------------------------------------------------------------- |
34 | Package / Vulnerable / Unaffected |
35 | ------------------------------------------------------------------- |
36 | 1 app-text/ptex < 3.1.10_p20071203 >= 3.1.10_p20071203 |
37 | |
38 | Description |
39 | =========== |
40 | |
41 | Multiple issues were found in the teTeX 2 codebase that PTeX builds |
42 | upon (GLSA 200709-17, GLSA 200711-26). PTeX also includes vulnerable |
43 | code from the GD library (GLSA 200708-05), from Xpdf (GLSA 200709-12, |
44 | GLSA 200711-22) and from T1Lib (GLSA 200710-12). |
45 | |
46 | Impact |
47 | ====== |
48 | |
49 | Remote attackers could possibly execute arbitrary code and local |
50 | attackers could possibly overwrite arbitrary files with the privileges |
51 | of the user running PTeX via multiple vectors, e.g. enticing users to |
52 | open specially crafted files. |
53 | |
54 | Workaround |
55 | ========== |
56 | |
57 | There is no known workaround at this time. |
58 | |
59 | Resolution |
60 | ========== |
61 | |
62 | All PTeX users should upgrade to the latest version: |
63 | |
64 | # emerge --sync |
65 | # emerge --ask --oneshot --verbose ">=app-text/ptex-3.1.10_p20071203" |
