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 . A heap-based buffer overflow in ClamAV 0.92.1 allowed remote attackers to execute arbitrary code via a crafted PeSpin packed PE binary . 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 . An unspecified vulnerability in ClamAV prior to 0.92.1 triggered heap corruption . A buffer overflow in ClamAV 0.92 and 0.92.1 allowed remote attackers to execute arbitrary code via a crafted Upack PE file . ClamAV prior to 0.93 allowed remote attackers to cause a denial of service via a crafted ARJ archive . A heap-based buffer overflow in ClamAV 0.92.1 allowed remote attackers to execute arbitrary code via a crafted WWPack compressed PE binary . ClamAV prior to 0.93 allowed remote attackers to bypass the scanning engine via a RAR file with an invalid version number . A vulnerability in rfc2231 handling in ClamAV prior to 0.93 allowed remote attackers to cause a denial of service via a crafted message that produced a string that was not null terminated, triggering a buffer over-read . A vulnerability in libclamunrar in ClamAV prior to 0.93 allowed remote attackers to cause a denial of service via a crafted RAR file . 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.
