Oracle Outside In 8.5.3 Heap-Based Buffer Overflows / OOB Write
Posted Jul 20, 2018
Authored by Behzad Najjarpour Jabbari | Site secunia.com

Secunia Research has discovered multiple vulnerabilities in Oracle Outside In Technology, which can be exploited by malicious people to compromise a vulnerable system. An error within the "VwStreamRead()" function (vsdrw.dll) can be exploited to cause a heap-based buffer overflow. A boundary error in the vsxl5.dll can be exploited to cause a heap-based buffer overflow. Another boundary error in the vsxl5.dll can be exploited to cause a heap-based buffer overflow. An integer underflow error within the "VwStreamOpen()" function (vswk6.dll) can be exploited to cause an out-of-bounds write memory access. The vulnerabilities are confirmed in version 8.5.3. Other versions may also be affected.

8) About Flexera

Flexera helps application producers and enterprises increase
application usage and the value they derive from their software.

http://www.flexera.com

Flexera delivers market-leading Software Vulnerability Management
solutions enabling enterprises to proactively identify and
remediate software vulnerabilities, effectively reducing the risk of
costly security breaches.

https://www.flexera.com/enterprise/products/

Flexera supports and contributes to the community in several
ways. We have always believed that reliable vulnerability
intelligence and tools to aid identifying and fixing vulnerabilities
should be freely available for consumers to ensure that users,
who care about their online privacy and security, can stay secure.
Only a few vendors address vulnerabilities in a proper way and help
users get updated and stay secure. End-users (whether private
individuals or businesses) are otherwise left largely alone, and
that is why back in 2002, Secunia Research started investigating,
coordinating disclosure and verifying software vulnerabilities.
In 2016, Secunia Research became a part of Flexera and today
our in-house software vulnerability research remains the core of
the Software Vulnerability Management products at Flexera.

https://www.flexera.com/enterprise/company/about/secunia-research/

The public Secunia Advisory database contains information for
researchers, security enthusiasts, and consumers to lookup individual
products and vulnerabilities and assess, whether they need to take
any actions to secure their systems or whether a given vulnerability
has already been discovered.
