15 Synopsis
16 ========
17
18 pstotext contains a vulnerability which can potentially result in the
19 execution of arbitrary code.
20
21 Background
22 ==========
23
24 pstotext is a program that works with GhostScript to extract plain text
25 from PostScript and PDF files.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 app-text/pstotext < 1.8g-r1 >= 1.8g-r1
34
35 Description
36 ===========
37
38 Max Vozeler reported that pstotext calls the GhostScript interpreter on
39 untrusted PostScript files without specifying the -dSAFER option.
40
41 Impact
42 ======
43
44 An attacker could craft a malicious PostScript file and entice a user
45 to run pstotext on it, resulting in the execution of arbitrary commands
46 with the permissions of the user running pstotext.
47
48 Workaround
49 ==========
50
51 There is no known workaround at this time.
52
53 Resolution
54 ==========
55
56 All pstotext users should upgrade to the latest version:
57
58 # emerge --sync
59 # emerge --ask --oneshot --verbose ">=app-text/pstotext-1.8g-r1"
