Title

freexl堆缓冲区溢出漏洞

Description

FreeXL是软件开发者Alessandro Furieri所研发的一个开源的用于从Excel（.xls）电子表格中提取有效数据的库。 FreeXL 1.0.3版本中存在堆缓冲区溢出漏洞，由于程序未能充分的对用户提交的数据执行边界检测，导致复制数据的大小超过了缓冲区的空间。远程攻击者可利用该漏洞在受影响应用程序上下文中执行任意代码或造成拒绝服务。

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
