Multiple vulnerabilities have been found in Xerces-C++, the worst of which may allow remote attackers to execute arbitrary code.
| Package | Arch | Vulnerable | Unaffected |

| dev-libs/xerces-c | * | < 3.1.4-r1 | >= 3.1.4-r1 |
Xerces-C++ is a validating XML parser written in a portable subset of C++.
Multiple vulnerabilities have been discovered in Xerces-C++. Please review the CVE identifiers referenced below for details.
A remote attacker could entice a user to process a specially crafted file, possibly resulting in the remote execution of arbitrary code with the privileges of the process, or a Denial of Service condition.
There is no known workaround at this time.
All Xerces-C++ users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/xerces-c-3.1.4-r1"
An error in Xerces-C++ allows for a Denial of Service via malicious XML schema files.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/xerces-c | * | < 3.0.0-r1 | >= 3.0.0-r1 |
Xerces-C++ is a validating XML parser written in a portable subset of C++.
Frank Rast reported that the XML parser in Xerces-C++ does not correctly handle an XML schema definition with a large maxOccurs value, which triggers excessive memory consumption during the validation of an XML file.
A remote attacker could entice a user or automated system to validate an XML file using a specially crafted XML schema file, leading to a Denial of Service (stack consumption and crash).
There is no known workaround at this time.
All Xerces-C++ users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/xerces-c-3.0.0-r1"
