[QSA-0622152] Security Bundle

Qlustar Security Advisory 0622152

June 22, 2015


Summary:

Security bundle. A Qlustar security bundle is a cumulative update of packages that are taken from upstream Debian/Ubuntu without modification. Only packages that are used in a typical HPC/Storage cluster installation are mentioned in Qlustar Security Advisories. Other non-HPC related updates also enter the Qlustar repository, but their functionality is not separately verified by the Qlustar team. To track these updates subscribe to the general security mailing lists of Debian/Ubuntu.


Package(s)       : see upstream description of individual package
Qlustar releases : 9.0
Affected versions: All versions prior to this update
Vulnerability    : see upstream description of individual package
Problem type     : see upstream description of individual package
Qlustar-specific : no
CVE Id(s)        : see upstream description of individual package

This update includes several security related package updates from Debian/Ubuntu. The following list provides references to the upstream security report of the corresponding packages. You can view the original upstream advisory by clicking on the corresponding title.

OpenSSL vulnerabilities

Praveen Kariyanahalli, Ivan Fratric and Felix Groebert discovered that OpenSSL incorrectly handled memory when buffering DTLS data. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code.

Joseph Barr-Pixton discovered that OpenSSL incorrectly handled malformed ECParameters structures. A remote attacker could use this issue to cause OpenSSL to hang, resulting in a denial of service.

Robert Swiecki and Hanno Böck discovered that OpenSSL incorrectly handled certain ASN1_TIME strings. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service.

Michal Zalewski discovered that OpenSSL incorrectly handled missing content when parsing ASN.1-encoded PKCS#7 blobs. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service.

Emilia Käsper discovered that OpenSSL incorrectly handled NewSessionTicket when being used by a multi-threaded client. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service.

Johannes Bauer discovered that OpenSSL incorrectly handled verifying signedData messages using the CMS code. A remote attacker could use this issue to cause OpenSSL to hang, resulting in a denial of service.

As a security improvement, this update also modifies OpenSSL behaviour to reject DH key sizes below 768 bits, preventing a possible downgrade attack.

QEMU vulnerabilities

Matt Tait discovered that QEMU incorrectly handled the virtual PCNET driver. A malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process.

Kurt Seifried discovered that QEMU incorrectly handled certain temporary files. A local attacker could use this issue to cause a denial of service.

CUPS vulnerabilities

It was discovered that CUPS incorrectly handled reference counting when handling localized strings. A remote attacker could use this issue to escalate permissions, upload a replacement CUPS configuration file, and execute arbitrary code.

It was discovered that the CUPS templating engine contained a cross-site scripting issue. A remote attacker could use this issue to bypass default configuration settings.

Qt vulnerabilities

Wolfgang Schenk discovered that Qt incorrectly handled certain malformed GIF images. If a user or automated system were tricked into opening a specially crafted GIF image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service.

Fabian Vogt discovered that Qt incorrectly handled certain malformed BMP images. If a user or automated system were tricked into opening a specially crafted BMP image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service.

Richard Moore and Fabian Vogt discovered that Qt incorrectly handled certain malformed BMP images. If a user or automated system were tricked into opening a specially crafted BMP image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service, or possibly execute arbitrary code.

Richard Moore and Fabian Vogt discovered that Qt incorrectly handled certain malformed ICO images. If a user or automated system were tricked into opening a specially crafted ICO image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service, or possibly execute arbitrary code.

Richard Moore and Fabian Vogt discovered that Qt incorrectly handled certain malformed GIF images. If a user or automated system were tricked into opening a specially crafted GIF image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service, or possibly execute arbitrary code.

OpenLDAP vulnerabilities

Michael Vishchers discovered that OpenLDAP improperly counted references when the rwm overlay was used. A remote attacker could use this issue to cause OpenLDAP to crash, resulting in a denial of service.

It was discovered that OpenLDAP incorrectly handled certain empty attribute lists in search requests. A remote attacker could use this issue to cause OpenLDAP to crash, resulting in a denial of service.
