Open Source is Getting Safer

Open source is not unsafe by nature, and a new report has numbers to back that up. If your software is unsafe, blame programming, not the license.

How safe is open source software? Critics argue that due to its open nature, the source code is open to engineers but also to hackers. Another accusation is that OSS needs frequent patching, and that response to that requirement can be slow.

Now, there's empirical evidence that the security of OSS has dramatically improved over the last decade. According to a study from Synopsys, a Silicon Valley based firm that specializes in application security testing, secure software development practices that make OSS safer are becoming mainstream.

One big indicator of the continued development of secure software development practices is the apparent level of care taken by teams when using a continuous integration/continuous deployment (CI/CD) methodology. Since January 2016, Synopsys has looked at 4,117 active OSS projects, and about 50% of them use Travis CI, a distributed continuous integration service used to build and test software projects hosted at GitHub.

Synopsys identified more than 1.1 million defects in active OSS projects, leading to the remediation of more than 600,000 defects. This involved the analysis of approximately 760 million lines of open source code across several languages, including C/C++, C#, Java, JavaScript, Ruby, PHP and Python.

The report findings are derived from security data collected over the past decade through Synopsys' own automated static analysis tools, called Coverity and originally created in the Computer Systems Laboratory at Stanford University. In a nutshell, static analysis allows bugs to be identified without ever having to run the software. It applies heuristics to a program's syntax tree, finding defects well in advance of release, limiting the potential impact of flaws.

"Bugs in software will continue to exist while development remains a human endeavor, but the ability fix and respond quickly to vulnerabilities puts OSS at an advantage," Mel Llaguno, open source solution manager for Synopsys Software Integrity Group, told Security Now.

Synopsys said that according to its customers, up to 90% of code shipped in software now consist of OSS, emphasizing just how vital security is during the development process. Also, since it's OSS, bug issues and fixes can be shared among the open source community, speeding troubleshooting.

"Due to the ubiquity of open source and the vital role it plays in virtually all types of software, understanding and managing its risks can no longer be optional," said Andreas Kuehlmann, senior vice president and general manager at Synopsys Software Integrity Group. "The report highlights the progress of some of the most mature and widely used open source projects, and it provides invaluable insights for the broader software community that depends on the integrity of open source."

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...
CVE-2020-15211
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...
CVE-2020-15212
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
