Two vulnerabilities have been identified in Squid, which could be exploited by attackers to cause a denial of service.
The first issue is due to errors in the "ftpListingFinish()" and "ftpHtmlifyListEntry()" [ftp.c] functions when processing certain FTP URIs, which could be exploited by attackers to crash a vulnerable proxy via a malicious URL.
The second issue is due to an infinite loop in "aclMatchExternal()" and "externalAclLookup()" [external_acl.c] when the proxy is under high load, which could be exploited to cause a denial of service.
