IBM Informix 11.10.xc1

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.

Integer overflow in librpc.dll in portmap.exe (aka the ISM Portmapper service) in ISM before 2.20.TC1.117 in IBM Informix Dynamic Server (IDS) 7.x before 7.31.xD11, 9.x before 9.40.xC10, 10.00 before 10.00.xC8, and 11.10 before 11.10.xC2 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted parameter size, aka idsdb00146931, idsdb00146930, idsdb00146929, and idsdb00138308.

Stack-based buffer overflow in IBM Informix Dynamic Server (IDS) 7.x through 7.31, 9.x through 9.40, 10.00 before 10.00.xC10, 11.10 before 11.10.xC3, and 11.50 before 11.50.xC3 allows remote authenticated users to execute arbitrary code via long DBINFO keyword arguments in a SQL statement, aka idsdb00165017, idsdb00165019, idsdb00165021, idsdb00165022, and idsdb00165023.

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.
