+ ClamAV is a GPL virus scanner. +

+
+ +

+ Several vulnerabilities were discovered in ClamAV by various + researchers: +

+
  • Victor Stinner (INL) discovered that the OLE2 + parser may enter in an infinite loop (CVE-2007-2650).
  • +
  • A + boundary error was also reported by an anonymous researcher in the file + unsp.c, which might lead to a buffer overflow (CVE-2007-3023).
  • +
  • The file unrar.c contains a heap-based buffer overflow via a + modified vm_codesize value from a RAR file (CVE-2007-3123).
  • +
  • The RAR parsing engine can be bypassed via a RAR file with a header + flag value of 10 (CVE-2007-3122).
  • +
  • The cli_gentempstream() + function from clamdscan creates temporary files with insecure + permissions (CVE-2007-3024).
  • +
+
+ +

+ A remote attacker could send a specially crafted file to the scanner, + possibly triggering one of the vulnerabilities. The two buffer + overflows are reported to only cause Denial of Service. This would lead + to a Denial of Service by CPU consumption or a crash of the scanner. + The insecure temporary file creation vulnerability could be used by a + local user to access sensitive data. +

+
+ +

+ There is no known workaround at this time. +

+
+ +

+ All ClamAV users should upgrade to the latest version: +

+ + # emerge --sync + # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.90.3" +
