Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to a bug in Google's Chrome browser causing it to crash when encountering a specific text string is reminiscent of the iPhone "Effective Power" bug found earlier that year, which could also be used to crash iPhones by sending a message. This similarity suggests that software failure incidents involving specific text strings causing crashes have happened before within the same organization (Google) or with its products and services [51427]. (b) The article does not provide specific information about similar incidents happening at other organizations or with their products and services. Therefore, there is no evidence to suggest that this particular type of software failure incident has occurred elsewhere [51427].
Phase (Design/Operation) design (a) The software failure incident in Article 51427 can be attributed to a design issue. The bug in Google's Chrome browser causing it to crash when interacting with a specific 16-character text string on a web page was a result of a flaw in the system development. The bug was discovered by a security researcher and reported to Google, leading to developers fixing the issue in the open-source base for Chrome. The fix needed time to migrate through the developer and beta builds to the stable version, indicating a design-related failure in the system development process [51427]. (b) The software failure incident in Article 51427 does not directly point to an operation-related failure. The crash in Chrome was triggered by a specific text string on a web page, and there is no mention of the failure being caused by the operation or misuse of the system. The incident primarily highlights a design flaw in the browser that led to the crash when interacting with the text string, rather than an operational issue [51427].
Boundary (Internal/External) within_system (a) within_system: The software failure incident in this case, the bug in Google's Chrome browser causing it to crash when interacting with a specific 16-character text string, is a result of an issue originating from within the system itself. The bug was discovered by a security researcher and reported to Google, leading to Chromium developers fixing the issue in the open-source base for Chrome [51427]. (b) outside_system: There is no specific mention in the article about contributing factors originating from outside the system leading to this software failure incident.
Nature (Human/Non-human) non-human_actions (a) The software failure incident in Article 51427 occurred due to a bug in Google's Chrome browser. The bug was related to a specific 16-character text string placed on a web page, which when interacted with, caused the browser to crash. This bug was not introduced by human actions but rather was a result of a coding flaw or issue within the browser itself. The bug was discovered by a security researcher and reported to Google for fixing [51427].
Dimension (Hardware/Software) software (a) The software failure incident in Article 51427 was not attributed to hardware issues. The bug in Google's Chrome browser causing crashes was specifically related to a 16-character text string placed on a web page, indicating a software-related issue. (b) The software failure incident in Article 51427 was caused by a bug in Google's Chrome browser. The bug was related to processing a specific 16-character text string, which led to the browser crashing when interacting with that string on a web page. This clearly points to a software-related failure.
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in Article 51427 was non-malicious. The incident was caused by a bug in Google's Chrome browser that crashed when interacting with a specific 16-character text string on a web page. The bug was discovered by a security researcher and reported to Google for a fix. The bug affected the current release version of Chrome on Windows and OS X but did not affect Chrome on Android devices. The developers fixed the issue in the open-source base for Chrome, and the fix was expected to migrate through the developer and beta builds to the stable version of Chrome [51427].
Intent (Poor/Accidental Decisions) accidental_decisions (a) The software failure incident in Article 51427 was not due to poor decisions but rather a bug in Google's Chrome browser caused by a specific text string placed on a web page. The bug was discovered by a security researcher and reported to Google, leading to a fix being implemented by Chromium developers [51427].
Capability (Incompetence/Accidental) accidental (a) The software failure incident in Article 51427 was not attributed to development incompetence. The bug in Google's Chrome browser causing crashes when interacting with a specific text string was discovered by a security researcher and promptly reported to Google for resolution. The bug was acknowledged and fixed by Chromium developers, indicating a proactive response to address the issue [51427]. (b) The software failure incident in Article 51427 was accidental in nature. The bug causing Chrome to crash when encountering a specific text string was not intentionally introduced but rather a result of how the browser processed certain characters in a URL. The incident was described as a simple web URL bug that could lead to crashes, highlighting an unintended consequence of the software's behavior [51427].
Duration temporary (a) The software failure incident described in Article 51427 is temporary. The bug in Google's Chrome browser, caused by a specific 16-character text string, led to crashes when interacting with it on a web page. This bug affected the current release version of Chrome on Windows and OS X but did not impact Chrome on Android devices. The issue was reported to Google, and Chromium developers fixed it in the latest revision of the open-source base for Chrome. However, the fix needed time to migrate through the developer and beta builds to the stable version of Chrome considered a full release. This indicates that the software failure incident was temporary and not permanent [51427].
Behaviour crash (a) The software failure incident described in Article 51427 is related to a crash behavior. The bug in Google's Chrome browser causes it to crash when clicking on or mousing over a specific 16-character text string placed on a web page. This crash behavior results in the current Chrome tab or the whole browser crashing, potentially causing loss of work in progress [51427].
