The XP Server process (xp_server) in Sybase Adaptive Server Enterprise (ASE) XP Server 12.x before 12.5.3 ESD#1 allows attackers to cause a denial of service (process crash) via malformed data sent to the XP Server TCP port.

Multiple stack-based buffer overflows in Sybase Adaptive Server Enterprise (ASE) 12.x before 12.5.3 ESD#1 allow remote authenticated users to execute arbitrary code via the (1) attrib_valid function, (2) covert function, (3) declare statement, or (4) a crafted query plan, or remote authenticated users with database owner or "sa" role privileges to execute arbitrary code via (5) a crafted install java statement.

Sybase Adaptive Server Enterprise (ASE) 12.5 allows remote attackers to cause a denial of service (hang) via a remote password array with an invalid length, which triggers a heap-based buffer overflow.

Sybase Enterprise Application Server 4.0, when running on Windows, allows remote attackers to retrieve files in the WEB-INF directory, which contains Java class files and configuration information, via a request to the WEB-INF directory with a trailing dot ("WEB-INF.").

Multiple buffer overflows in Sybase Adaptive Server 12.0 and 12.5 allow remote attackers to execute arbitrary code via (1) a long parameter to the xp_freedll extended stored procedure or (2) a long database name argument to the DBCC CHECKVERIFY function.

Sybase Adaptive Server Anywhere Database Engine 6.0.3.2747 and earlier as included with Symantec Ghost 6.5 allows a remote attacker to create a denial of service by sending large (> 45Kb) amounts of data to port 2638.
