Format string vulnerability in clamav-milter for Clam AntiVirus 0.60 through 0.60p, and other versions before 0.65, allows remote attackers to cause a denial of service and possibly execute arbitrary code via format string specifiers in the email address argument of a "MAIL FROM" command.
The filecopy function in misc.c in Clam AntiVirus (ClamAV) before 0.85, on Mac OS, allows remote attackers to execute arbitrary code via a virus in a filename that contains shell metacharacters, which are not properly handled when HFS permissions prevent the file from being deleted and ditto is invoked.
The FSG unpacker (fsg.c) in Clam AntiVirus (ClamAV) 0.80 through 0.87 allows remote attackers to cause "memory corruption" and execute arbitrary code via a crafted FSG 1.33 file.
Multiple integer overflows in the (1) TNEF, (2) CHM, or (3) FSG file format processors in libclamav for Clam AntiVirus (ClamAV) 0.86.1 and earlier allow remote attackers to gain privileges via a crafted e-mail message.
Heap-based buffer overflow in libclamav/upx.c in Clam Antivirus (ClamAV) before 0.88 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted UPX files.
Integer overflow in ClamAV 0.88.1 and 0.88.4, and other versions before 0.88.5, allows remote attackers to cause a denial of service (scanning service crash) and execute arbitrary code via a crafted Portable Executable (PE) file that leads to a heap-based buffer overflow when less memory is allocated than expected.
Integer signedness error in the (1) cabunstore and (2) cabextract functions in libclamav/cab.c in Clam AntiVirus (ClamAV) before 0.90.2 allow remote attackers to execute arbitrary code via a crafted CHM file that contains a negative integer, which passes a signed comparison and leads to a stack-based buffer overflow.
Clam AntiVirus ClamAV before 0.90 does not close open file descriptors under certain conditions, which allows remote attackers to cause a denial of service (file descriptor consumption and failed scans) via CAB archives with a cabinet header record length of zero, which causes a function to return without closing a file descriptor.
Integer overflow in libclamav in ClamAV before 0.92 allows remote attackers to execute arbitrary code via a crafted MEW packed PE file, which triggers a heap-based buffer overflow.
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.
freshclam in (1) Clam Antivirus (ClamAV) 0.88 and (2) ClamXav 1.0.3h and earlier does not drop privileges before processing the config-file command line option, which allows local users to read portions of arbitrary files when an error message displays the first line of the target file.
The chmdecompressstream function in libclamav/chmunpack.c in Clam AntiVirus (ClamAV) before 0.90.2 leaks file descriptors, which has unknown impact and attack vectors involving a crafted CHM file, a different vulnerability than CVE-2007-0897. NOTE: some of these details are obtained from third party information.
Off-by-one error in ClamAV before 0.92 allows remote attackers to execute arbitrary code via a crafted MS-ZIP compressed CAB file.
Directory traversal vulnerability in clamd in Clam AntiVirus ClamAV before 0.90 allows remote attackers to overwrite arbitrary files via a .. (dot dot) in the id MIME header parameter in a multi-part message.
Multiple interpretation error in unspecified versions of ClamAV Antivirus allows remote attackers to bypass virus detection via a malicious executable in a specially crafted RAR file with malformed central and local headers, which can still be opened by products such as Winrar and PowerZip, even though they are rejected as corrupted by Winzip and BitZipper.
Integer overflow in the cliscanpe function in the PE header parser (libclamav/pe.c) in Clam AntiVirus (ClamAV) before 0.88.1, when ArchiveMaxFileSize is disabled, allows remote attackers to cause a denial of service and possibly execute arbitrary code.
Buffer overflow in the getdatabase function in the HTTP client in Freshclam in ClamAV 0.80 to 0.88.1 might allow remote web servers to execute arbitrary code via long HTTP headers.
libclamav/fsg.c in Clam AntiVirus (ClamAV) before 0.87 allows remote attackers to cause a denial of service (infinite loop) via a crafted FSG packed executable.
The MS-Expand file handling in Clam AntiVirus (ClamAV) before 0.86 allows remote attackers to cause a denial of service (file descriptor and memory consumption) via a crafted file that causes repeated errors in the climsexpand function.
ClamAV 0.80 and earlier allows remote attackers to bypass virus scanning via a base64 encoded image in a data: (RFC 2397) URL.
The tnefattachment function in tnef.c for Clam AntiVirus (ClamAV) before 0.87.1 allows remote attackers to cause a denial of service (infinite loop and memory exhaustion) via a crafted value in a CAB file that causes ClamAV to repeatedly scan the same block.
ClamAV 0.80 and earlier allows remote attackers to cause a denial of service (clamd daemon crash) via a ZIP file with malformed headers.
Unspecified vulnerability in ClamAV before 0.88.5 allows remote attackers to cause a denial of service (scanning service crash) via a crafted Compressed HTML Help (CHM) file that causes ClamAV to "read an invalid memory location."
