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."

Unspecified vulnerability in the bzip2 decompression algorithm in nsis/bzlib_private.h in ClamAV before 0.92 has unknown impact and remote attack vectors.

ClamAV 0.92 allows local users to overwrite arbitrary files via a symlink attack on (1) temporary files used by the cli_gentempfd function in libclamav/others.c or on (2) .ascii files used by sigtool, when utf16-decode is enabled.

ClamAV 0.92 does not recognize Base64 UUEncoded archives, which allows remote attackers to bypass the scanner via a Base64-UUEncoded file.

Unspecified vulnerability in ClamAV 0.91.1 and 0.91.2 allows remote attackers to execute arbitrary code via a crafted e-mail message. NOTE: this information is based upon a vague advisory by a vulnerability information sales organization that does not coordinate with vendors or release actionable advisories. A CVE has been assigned for tracking purposes, but duplicates with other CVEs are difficult to determine.

The RAR VM (unrarvm.c) in Clam Antivirus (ClamAV) before 0.91 allows user-assisted remote attackers to cause a denial of service (crash) via a crafted RAR archive, resulting in a NULL pointer dereference.

libclamav/others.c in ClamAV before 0.90.3 and 0.91 before 0.91rc1 uses insecure permissions for temporary files that are created by the cli_gentempstream function in clamd/clamdscan, which might allow local users to read sensitive files.

Unspecified vulnerability in libclamav/phishcheck.c in ClamAV before 0.90.3 and 0.91 before 0.91rc1, when running on Solaris, allows remote attackers to cause a denial of service (hang) via unknown vectors related to the isURL function and regular expressions.

unsp.c in ClamAV before 0.90.3 and 0.91 before 0.91rc1 does not properly calculate the end of a certain buffer, with unknown impact and remote attack vectors.

The parsing engine in ClamAV before 0.90.3 and 0.91 before 0.91rc1 allows remote attackers to bypass scanning via a RAR file with a header flag value of 10, which can be processed by WinRAR.
