Multiple vulnerabilities have been reported in Sybase Adaptive Server Enterprise, which can be exploited by malicious, local users to disclose potentially sensitive information and by malicious users to disclose potentially sensitive information, manipulate certain data, conduct SQL injection attacks, cause a DoS (Denial of Service), bypass certain security restrictions, and compromise a vulnerable system.
1) An error when handling a hacmpmsgxchg built-in procedure invocation can be exploited to gain "sa_role" privileges.
2) An unspecified error can be exploited to disclose certain information.
3) An error when handling the ssl_admin built-in function can be exploited to cause a DoS condition via an overly long argument.
4) An error in the config_admin built-in function can be exploited to cause a buffer overflow.
5) An unspecified error can be exploited to disclose certain information.
The vulnerabilities #1 through #5 are reported in all 15.x versions.
6) An error when handling installation log files can be exploited to gain knowledge of e.g. the cleartext password for the built-in "sa" account.
7) Input passed via the UPDATE STATISTICS command is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
8) An error when handling the TRANSFER TABLE command can be exploited to create arbitrary files on the database server filesystem via directory traversal sequences.
9) An error when handling the set_password built-in function can be exploited to cause a stack-based buffer overflow via an overly long argument.
Successful exploitation of the vulnerabilities #4 and #9 may allow execution of arbitrary code.
The vulnerabilities #6 through #9 are reported in versions 15.0.3 and later.
10) An error when handling the hacmpmsgxchg built-in procedure can be exploited to cause a DoS condition via missing parameters.
The vulnerability #10 is reported in versions 15.7 and later.
Solution: Update to a fixed version (please see the vendor's advisory for details).
