Clam Anti virus Clamav 0.90 Rc1.1

Stack consumption vulnerability in libclamav/special.c in ClamAV before 0.94.2 allows remote attackers to cause a denial of service (daemon crash) via a crafted JPEG file, related to the cli_check_jpeg_exploit, jpeg_check_photoshop, and jpeg_check_photoshop_8bim functions.

Off-by-one error in the get_unicode_name function (libclamav/vba_extract.c) in Clam Anti-Virus (ClamAV) before 0.94.1 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted VBA project file, which triggers a heap-based buffer overflow.

libclamav/chmunpack.c in the chm-parser in ClamAV before 0.94 allows remote attackers to cause a denial of service (application crash) via a malformed CHM file, related to an "invalid memory access."

libclamav/petite.c in ClamAV before 0.93.1 allows remote attackers to cause a denial of service via a crafted Petite file that triggers an out-of-bounds read.

libclamunrar in ClamAV before 0.93 allows remote attackers to cause a denial of service (crash) via crafted RAR files that trigger "memory problems," as demonstrated by the PROTOS GENOME test suite for Archive Formats.

The rfc2231 function in message.c in libclamav in ClamAV before 0.93 allows remote attackers to cause a denial of service (crash) via a crafted message that produces a string that is not null terminated, which triggers a buffer over-read.

ClamAV before 0.93 allows remote attackers to bypass the scanning enging via a RAR file with an invalid version number, which cannot be parsed by ClamAV but can be extracted by Winrar.

ClamAV before 0.93 allows remote attackers to cause a denial of service (CPU consumption) via a crafted ARJ archive, as demonstrated by the PROTOS GENOME test suite for Archive Formats.

Integer overflow in the cli_scanpe function in libclamav in ClamAV before 0.92.1, as used in clamd, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted Petite packed PE file, which triggers a heap-based buffer overflow.

Off-by-one error in ClamAV before 0.92 allows remote attackers to execute arbitrary code via a crafted MS-ZIP compressed CAB file.

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.

clamav-milter in ClamAV before 0.91.2, when run in black hole mode, allows remote attackers to execute arbitrary commands via shell metacharacters that are used in a certain popen call, involving the "recipient field of sendmail."

ClamAV before 0.91.2, as used in Kolab Server 2.0 through 2.2beta1 and other products, allows remote attackers to cause a denial of service (application crash) via (1) a crafted RTF file, which triggers a NULL dereference in the cli_scanrtf function in libclamav/rtf.c; or (2) a crafted HTML document with a data: URI, which triggers a NULL dereference in the cli_html_normalise function in libclamav/htmlnorm.c. NOTE: some of these details are obtained from third party information.

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.

unrar.c in libclamav in ClamAV before 0.90.3 and 0.91 before 0.91rc1 allows remote attackers to cause a denial of service (core dump) via a crafted RAR file with a modified vm_codesize value, which triggers a heap-based buffer overflow.

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.

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.

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.

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.

Integer signedness error in the (1) cab_unstore and (2) cab_extract 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.

The chm_decompress_stream 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.
