Unspecified vulnerability in Skype allows remote attackers to cause a denial of service (server hang) via unknown vectors related to sending long URIs, as claimed to be actively exploited on 20070817 using a "call to a specific number." NOTE: this identifier is for the en.securitylab.ru disclosure. According to the vendor, this issue is separate from the "sign-on issues" that reduced Skype service on 20070817, which appears to be a site-specific problem. As of 20070821, it is not clear whether this issue is simply a symptom of the larger sign-on problem.

Security readout for executives and security teams

This is an old, poorly specified Skype denial-of-service report. The available record says attackers may have been able to make Skype service components hang, but affected versions, root cause, and scope are not identified. Vendor commentary also separated it from the wider August 2007 Skype sign-on outage. Exposure cannot be reliably bounded from the provided sources. Organizations historically dependent on Skype around August 2007 were the plausible concern. The bundle does not identify affected versions, supported modern products, or current exposure. Treat this as a historical availability-risk item with incomplete evidence. It does not justify emergency action without legacy Skype exposure, but unresolved reliance on old Skype software should be retired or governed. Mitigation focus: Check vendor Skype or Microsoft guidance for any archival advisory or fix.; Avoid relying on this CVE record alone for patch decisions.; Maintain alternate communications if Skype availability is operationally critical..
