Multiple vulnerabilities have benn identified in Clam AntiVirus (ClamAV), which could be exploited by remote attackers to execute arbitrary commands or cause a denial of service.
The first issue is due to an integer overflow error in the PE header parser [libclamav/pe.c], which could be exploited by attackers to compromise a vulnerable system where the "ArchiveMaxFileSize" option has been disabled.
The second flaw is due to format string errors in certain logging functions [shared/output.c], which could be exploited by attackers to execute arbitrary commands.
The third vulnerability is due to an invalid memory access in the "cli_bitset_set()" [ibclamav/others.c] function, which could be exploited by attackers to crash a vulnerable application.
