-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SCO Security Advisory Subject: UnixWare 7.1.4 : Samba multiple security issues Advisory number: SCOSA-2005.17 Issue date: 2005 February 11 Cross reference: sr892475 fz530644 erg712754 sr892165 fz530486 erg712735 CAN-2004-0930 CAN-2004-0882 CAN-2004-1154 ______________________________________________________________________________ 1. Problem Description Samba provides file and print services to windows clients. Several security issues are fixed by this patch. The ms_fnmatch function in Samba 3.0.4 and 3.0.7 and possibly other versions allows remote authenticated users to cause a denial of service (CPU consumption) via a SAMBA request that contains multiple SCOSA-2005.17.in SCOSA-2005.17.txt samba.pkg (wildcard) characters. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0930 to this issue. Buffer overflow in the QFILEPATHINFO request handler in Samba 3.0.x through 3.0.7 may allow remote attackers to execute arbitrary code via a TRANSACT2_QFILEPATHINFO request with a small "maximum data bytes" value. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0882 to this issue. Integer overflow in the Samba daemon (smbd) in Samba 2.x and 3.0.x through 3.0.9 allows remote authenticated users to cause a denial of service (application crash) and possibly execute arbitrary code via a Samba request with a large number of security descriptors that triggers a heap-based buffer overflow. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1154 to this issue. 2.
