15 | Synopsis |
16 | ======== |
17 | |
18 | Multiple vulnerabilities in ClamAV may result in the remote execution |
19 | of arbitrary code. |
20 | |
21 | Background |
22 | ========== |
23 | |
24 | Clam AntiVirus is a free anti-virus toolkit for UNIX, designed |
25 | especially for e-mail scanning on mail gateways. |
26 | |
27 | Affected packages |
28 | ================= |
29 | |
30 | ------------------------------------------------------------------- |
31 | Package / Vulnerable / Unaffected |
32 | ------------------------------------------------------------------- |
33 | 1 app-antivirus/clamav < 0.93 >= 0.93 |
34 | |
35 | Description |
36 | =========== |
37 | |
38 | Multiple vulnerabilities have been reported: |
39 | |
40 | * Damian Put reported a heap-based buffer overflow when processing |
41 | PeSpin packed PE binaries (CVE-2008-0314). |
42 | |
43 | * Alin Rad Pop of Secunia Research reported a buffer overflow in the |
44 | cli_scanpe() function when processing Upack PE binaries |
45 | (CVE-2008-1100). |
46 | |
47 | * Hanno Boeck reported an infinite loop when processing ARJ archives |
48 | (CVE-2008-1387). |
49 | |
50 | * Damian Put and Thomas Pollet reported a heap-based buffer overflow |
51 | when processing WWPack compressed PE binaries (CVE-2008-1833). |
52 | |
53 | * A buffer over-read was discovered in the rfc2231() function when |
54 | producing a string that is not NULL terminated (CVE-2008-1836). |
55 | |
56 | * An unspecified vulnerability leading to "memory problems" when |
57 | scanning RAR files was reported (CVE-2008-1837). |
58 | |
59 | * Thierry Zoller reported that scanning of RAR files could be |
60 | circumvented (CVE-2008-1835). |
61 | |
62 | Impact |
63 | ====== |
64 | |
65 | A remote attacker could entice a user or automated system to scan a |
66 | specially crafted file, possibly leading to the execution of arbitrary |
67 | code with the privileges of the user running ClamAV (either a system |
68 | user or the "clamav" user if clamd is compromised), or a Denial of |
69 | Service. |
70 | |
71 | Workaround |
72 | ========== |
73 | |
74 | There is no known workaround at this time. |
75 | |
76 | Resolution |
77 | ========== |
78 | |
79 | All ClamAV users should upgrade to the latest version: |
80 | |
81 | # emerge --sync |
82 | # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.93" |
