Multiple stack-based buffer overflows in Command EXEC in Cisco IOS allow local users to gain privileges via unspecified vectors, aka (1) PSIRT-0474975756 and (2) PSIRT-0388256465. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.
CVE-2007-4295 1 Cisco 1 Ios 2025-04-09 6.8 MEDIUM N/A
Unspecified vulnerability in Cisco IOS 12.0 through 12.4 allows remote attackers to execute arbitrary code via a malformed SIP packet, aka CSCsi80749.
CVE-2007-2587 1 Cisco 1 Ios 2025-04-09 6.3 MEDIUM N/A
The IOS FTP Server in Cisco IOS 11.3 through 12.4 allows remote authenticated users to cause a denial of service (IOS reload) via unspecified vectors involving transferring files (aka bug ID CSCse29244).
CVE-2008-1447 6 Canonical, Cisco, Debian and 3 more 8 Ubuntu Linux, Ios, Debian Linux and 5 more 2025-04-09 5.0 MEDIUM 6.8 MEDIUM
The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2) Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction IDs and source ports, aka "DNS Insufficient Socket Entropy Vulnerability" or "the Kaminsky bug."
CVE-2007-0917 1 Cisco 1 Ios 2025-04-09 6.4 MEDIUM N/A
The Intrusion Prevention System (IPS) feature for Cisco IOS 12.4XE to 12.3T allows remote attackers to bypass IPS signatures that use regular expressions via fragmented packets.
