Integer signedness error in the authentication functionality in librpc.dll in the Informix Storage Manager (ISM) Portmapper service (aka portmap.exe), as used in IBM Informix Dynamic Server (IDS) 10.x before 10.00.TC9 and 11.x before 11.10.TC3 and EMC Legato NetWorker, allows remote attackers to execute arbitrary code via a crafted parameter size that triggers a stack-based buffer overflow.

Multiple buffer overflows in the authentication functionality in librpc.dll in the Informix Storage Manager (ISM) Portmapper service (aka portmap.exe), as used in IBM Informix Dynamic Server (IDS) 10.x before 10.00.TC9 and 11.x before 11.10.TC3, allow remote attackers to execute arbitrary code via a crafted parameter size.

IBM Informix Dynamic Server (IDS) 10.00 before 10.00.xC11, 11.10 before 11.10.xC4, and 11.50 before 11.50.xC5 allows remote attackers to cause a denial of service (memory corruption, assertion failure, and daemon crash) by sending a long password over a JDBC connection.

Multiple buffer overflows in oninit.exe in IBM Informix Dynamic Server (IDS) 7.x through 11.x allow (1) remote attackers to execute arbitrary code via a long password and (2) remote authenticated users to execute arbitrary code via a long DBPATH value.

Unspecified vulnerability in IBM Informix Dynamic Server (IDS) 7.x through 11.x allows remote attackers to gain privileges via a malformed connection request packet.

Multiple stack-based and heap-based buffer overflows in the Windows RPC components for IBM Informix Storage Manager (ISM), as used in Informix Dynamic Server (IDS) 10.00.xC8 and earlier and 11.10.xC2 and earlier, allow attackers to execute arbitrary code via crafted XDR requests.

onedcu in IBM Informix Dynamic Server (IDS) 10.x before 10.00.xC8 allows local users to create arbitrary files via the Trace file argument.

Directory traversal vulnerability in IBM Informix Dynamic Server (IDS) before 10.00.xC7W1 allows local users to gain privileges by referencing modified NLS message files through directory traversal sequences in the DBLANG environment variable.

Buffer overflow in IBM Informix Dynamic Server (IDS) before 9.40.TC7 and 10.00 before 10.00.TC3, when running on Windows, allows remote attackers to execute arbitrary code via a long username.

The ifx_load_internal function in IBM Informix Dynamic Server (IDS) allows remote authenticated users to execute arbitrary C code via the DllMain or _init function in a library, aka "C code UDR."

IBM Informix Dynamic Server (IDS) before 9.40.xC7 and 10.00 before 10.00.xC3 allows local users to cause a denial of service (crash) via unspecified vectors.

IBM Informix Dynamic Server (IDS) before 9.40.xC8 and 10.00 before 10.00.xC4 stores passwords in plaintext in shared memory, which allows local users to obtain passwords by reading the memory (product defects 171893, 171894, 173772).

IBM Informix Dynamic Server (IDS) before 9.40.xC7 and 10.00 before 10.00.xC3 does not use database creation permissions, which allows remote authenticated users to create arbitrary databases.
