3) Description of Vulnerabilities

Secunia Research has discovered multiple vulnerabilities in LibRaw,

which can be exploited by malicious people to cause a DoS (Denial of

Service).

1) An error related to the "LibRaw::panasonic_load_raw()" function

(dcraw_common.cpp) can be exploited to cause a heap-based buffer

overflow and subsequently cause a crash via a specially crafted TIFF

image.

2) An error within the "LibRaw::xtrans_interpolate()" function

(internal/dcraw_common.cpp) can be exploited to cause an invalid read

memory access.

The vulnerabilities are confirmed in version 0.18.5 and reported in

versions prior to 0.18.6.

======================================================================

4) Solution

Update to version 0.18.6.

8) About Flexera Software

Flexera helps application producers and enterprises increase

application usage and the value they derive from their software.

http://www.flexerasoftware.com/enterprise/company/about/

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.

http://www.flexerasoftware.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.

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
