The unmew11 function in libclamav/mew.c in libclamav in ClamAV before 0.92.1 has unknown impact and attack vectors that trigger "heap corruption."

Multiple vulnerabilities were discovered in ClamAV and corrected with the 0.93 release, including :

ClamAV 0.92 allowed local users to overwrite arbitrary files via a symlink attack on temporary files or on .ascii files in sigtool, when utf16-decode is enabled (CVE-2007-6595).

ClamAV 0.92 did not recognize Base64 uuencoded archives, which allowed remoted attackers to bypass the sanner via a base64-uuencoded file (CVE-2007-6596).

A heap-based buffer overflow in ClamAV 0.92.1 allowed remote attackers to execute arbitrary code via a crafted PeSpin packed PE binary (CVE-2008-0314).

An integer overflow in libclamav prior to 0.92.1 allowed remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted Petite packed PE file, which triggered a heap-based buffer overflow (CVE-2008-0318).

An unspecified vulnerability in ClamAV prior to 0.92.1 triggered heap corruption (CVE-2008-0728).

A buffer overflow in ClamAV 0.92 and 0.92.1 allowed remote attackers to execute arbitrary code via a crafted Upack PE file (CVE-2008-1100).

ClamAV prior to 0.93 allowed remote attackers to cause a denial of service (CPU consumption) via a crafted ARJ archive (CVE-2008-1387).

A heap-based buffer overflow in ClamAV 0.92.1 allowed remote attackers to execute arbitrary code via a crafted WWPack compressed PE binary (CVE-2008-1833).

ClamAV prior to 0.93 allowed remote attackers to bypass the scanning engine via a RAR file with an invalid version number (CVE-2008-1835).

A vulnerability in rfc2231 handling in ClamAV prior to 0.93 allowed remote attackers to cause a denial of service (crash) via a crafted message that produced a string that was not null terminated, triggering a buffer over-read (CVE-2008-1836).

A vulnerability in libclamunrar in ClamAV prior to 0.93 allowed remote attackers to cause a denial of service (crash) via a crafted RAR file (CVE-2008-1837).

Other bugs have also been corrected in 0.93 which is being provided with this update. Because this new version has increased the major of the libclamav library, updated dependent packages are also being provided.

The remote host is running a version of Mac OS X 10.5 or 10.4 that does not have the security update 2008-002 applied. 

This update contains several security fixes for a number of programs.

The remote host is affected by the vulnerability described in GLSA-200802-09 (ClamAV: Multiple vulnerabilities)

    An integer overflow has been reported in the 'cli_scanpe()' function in     file libclamav/pe.c (CVE-2008-0318). Another unspecified vulnerability     has been reported in file libclamav/mew.c (CVE-2008-0728).
  Impact :

    A remote attacker could entice a user or automated system to scan a     specially crafted file, possibly leading to the execution of arbitrary     code with the privileges of the user running ClamAV (either a system     user or the 'clamav' user if clamd is compromised).
  Workaround :

    There is no known workaround at this time.

This version upgrade to 0.92.1 fixes numerous flaws including some security problems (CVE-2008-0318, CVE-2008-0728).

Please note that the version number of the clamav library has changed with version 0.92. Programs linked against older libclamav therefore need to be updated as well.
