![]() ![]() “I’d say it might be wise to not ever allow hash values to be assigned directly from functions without a call to scalar. The Bugzilla developers have found fifteen instances where the problematic pattern occurred in its code and determined that four of them were exploitable to some degree, Markham said. “This allows an attacker to override values already in the hash (specified earlier), which may have already been validated, with values controlled by them.”ĬGI-based applications might be vulnerable is a similar way if developers didn’t take this behavior into consideration, but according to one reader who commented on Markham’s blog post, the issue has been known since 2006. ![]() “When assigning the result of a function call as a hash value, if the return value is a single scalar, all goes as you would expect, but if it’s an array, the second and subsequent values end up being added as key/value pairs in the hash as well,” Markham said in a post on his personal blog. The flaw might also have implications for other applications because according to Bugzilla developer Gervase Markham, the issue stems from a “Perl-specific security problem” involving the context in which functions called during hash value assignment are evaluated. “It is unknown whether any attacks have occurred as a result of this vulnerability but we recommend that Bugzilla installation administrators screen their current user lists for suspicious activity.” “Bugzilla administrators are urged to deploy the patch and upgrade their software immediately,” the Check Point researchers said. The Bugzilla Project released versions 4.0.15, 4.2.11, 4.4.6, and 4.5.6 to address this and other flaws that could also enable cross-site scripting, information leakage and social engineering attacks. The vulnerability affects all Bugzilla versions going back to 2.23.3, which was released in 2006. Furthermore, this access allows attackers to exploit design weaknesses, or even irreversibly destroy bug data, slowing down development.” “Software bug tracking data is typically closely guarded as it exposes software vulnerabilities and known issues. The Bugzilla Project shared a preliminary patch last week with major software projects that use the application, but the flaw has been in the software for a long time and it’s unclear whether anyone discovered and exploited it independently in the past.īy using the admin credentials obtained through this vulnerability, “attackers can then view and edit private and undisclosed bug details,” the Check Point researchers said in a blog post. Includes everything except for the weight tracker and meal planner.ĭownload OpenOffice.The vulnerability was discovered by security researchers from Check Point Software Technologies and was reported to the Bugzilla developers on Sept.

To fix the vulnerabilities, current versions of The Document Foundation (7.2.1) and Apache (4.1.11) are available for download. I designed these weight loss spreadsheets so that I could follow John Walker’s Hacker’s Diet using free ODS-compatible office suites, including LibreOffice / . By exploiting the vulnerabilities, the attacker is able to manipulate data to make it appear to have been signed by a trusted source. ![]()
