{"id": "SMNTC-71501", "type": "symantec", "bulletinFamily": "software", "title": "Microsoft Excel CVE-2014-6361 Memory Corruption Vulnerability", "description": "### Description\n\nMicrosoft Excel is prone to a memory-corruption vulnerability. Attackers can exploit this issue to execute arbitrary code in the context of the currently logged-in user. Failed attacks will cause denial-of-service conditions.\n\n### Technologies Affected\n\n * Microsoft Excel 2007 SP3 \n * Microsoft Excel 2010 SP1 (32-bit editions) \n * Microsoft Excel 2010 SP1 (64-bit editions) \n * Microsoft Excel 2010 SP2 (32-bit editions) \n * Microsoft Excel 2010 SP2 (64-bit editions) \n * Microsoft Excel 2013 (32-bit editions) \n * Microsoft Excel 2013 (64-bit editions) \n * Microsoft Excel 2013 RT \n * Microsoft Excel 2013 RT Service Pack 1 \n * Microsoft Excel 2013 Service Pack 1 (32-bit editions) \n * Microsoft Excel 2013 Service Pack 1 (64-bit editions) \n * Microsoft Office Compatibility Pack \n\n### Recommendations\n\n**Run all software as a nonprivileged user with minimal access rights.** \nTo reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.\n\n**Deploy network intrusion detection systems to monitor network traffic for malicious activity.** \nDeploy NIDS to monitor network traffic for signs of suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.\n\n**Do not accept or execute files from untrusted or unknown sources.** \nTo reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.\n\n**Do not follow links provided by unknown or untrusted sources.** \nWeb users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.\n\n**Implement multiple redundant layers of security.** \nSince this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.\n\nUpdates are available. Please see the references or vendor advisory for more information.\n", "published": "2014-12-09T00:00:00", "modified": "2014-12-09T00:00:00", "cvss": {"score": 9.3, "vector": "AV:NETWORK/AC:MEDIUM/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}, "href": "https://www.symantec.com/content/symantec/english/en/security-center/vulnerabilities/writeup.html/71501", "reporter": "Symantec Security Response", "references": [], "cvelist": ["CVE-2014-6361"], "lastseen": "2018-03-12T00:30:51", "viewCount": 1, "enchantments": {"score": {"value": 8.7, "vector": "NONE", "modified": "2018-03-12T00:30:51", "rev": 2}, "dependencies": {"references": [{"type": "cve", "idList": ["CVE-2014-6361"]}, {"type": "openvas", "idList": ["OPENVAS:1361412562310805024", "OPENVAS:1361412562310805023"]}, {"type": "nessus", "idList": ["SMB_NT_MS14-083.NASL"]}, {"type": "securityvulns", "idList": ["SECURITYVULNS:VULN:14212"]}, {"type": "kaspersky", "idList": ["KLA10616"]}], "modified": "2018-03-12T00:30:51", "rev": 2}, "vulnersScore": 8.7}, "affectedSoftware": [{"version": "2010 SP2 (32-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2013 Service Pack 1 (64-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2010 SP2 (64-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2010 SP1 (64-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2013 RT ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2013 RT Service Pack 1 ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2013 (32-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2007 SP3 ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2013 Service Pack 1 (32-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2013 (64-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}, {"version": "2010 SP1 (32-bit editions) ", "name": "Microsoft Excel", "operator": "eq"}], "immutableFields": []}
