A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences (for example, from start tag names) to the XML processing application on top of expat can lead to arbitrary code execution. This issue is dependent on how invalid UTF-8 is handled inside the XML processor.

An undisclosed vulnerability in IBM Rational DOORS 9.5.1 through 9.6.1.10 application allows an attacker to gain DOORS administrator privileges. IBM X-Force ID: 140208.

Apache Portable Runtime (APR) could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in the aprsocketsendv() function. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.

IBM Doors Web Access 9.5 and 9.6 could allow an attacker with physical access to the system to log into the application using previously stored credentials. IBM X-Force ID: 130914.

IBM DOORS Web Access is vulnerable to cross-site scripting. This vulnerability allows an unauthenticated attacker to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

Apache Portable Runtime Utility (APR-util) 1.6.0 and prior fail to validate the integrity of SDBM database files used by aprsdbm() functions, resulting in a possible out of bound read access. A local user with write access to the database can make a program or process using these functions crash, and cause a denial of service.

IBM DOORS 9.5 and 9.6 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 130411.

IBM Doors Web Access 9.5 and 9.6 could allow a remote attacker to hijack the clicking action of the victim. By persuading a victim to visit a malicious Web site, a remote attacker could exploit this vulnerability to hijack the victim's click actions and possibly launch further attacks against the victim. IBM X-Force ID: 129826.

IBM Doors Web Access 9.5 and 9.6 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 131763.

IBM Doors Web Access 9.5 and 9.6 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 130808.

IBM Doors Web Access 9.5 and 9.6 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 131769.

Peter Valchev discovered a flaw in the way expat handled malformed UTF-8 sequences when processing XML files. Incorrect UTF-8 sequenced could cause expat to fail to properly detect end of input and continue reading behind the end of input buffer. This results in a crash once reading reaches unmapped memory.
