Multiple vulnerabilities were identified in Clam AntiVirus, which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service.
The first issue is due to a buffer overflow error in "libclamav/fsg.c" when unpacking malformed FSG files, which could be exploited by remote attackers to execute arbitrary commands via a specially crafted file.
The second vulnerability is due to an infinite loop in "libclamav/tnef.c" when processing malformed TNEF files, which could be exploited by remote attackers to cause a denial of service.
The third flaw is due to an infinite loop in "libclamav/mspack/cabd.c" when processing malformed CAB files, which could be exploited by remote attackers to cause a denial of service.
