1.修復(fù)的CVE ·CVE-2018-21009 描述：0.66.0之前的Poppler在Parser:：makeStream中存在整數(shù)溢出解析器.cc. ·CVE-2019-10871 描述：在Poppler 0.74.0中發(fā)現(xiàn)了一個問題。函數(shù)PSOutputDev:：checkPageSlice中存在一個基于堆的緩沖區(qū)覆蓋PSOutputDev.cc. ·CVE-2019-11459 描述：GNOME evice到3.32.0版本的tiff文檔后端中的tiff_document_render（）和tiff_document_get_thumbnail（）函數(shù)沒有處理來自TIFFReadRGBAImageOriented（）的錯誤，導(dǎo)致在處理某些tiff圖像文件時未初始化內(nèi)存使用。 ·CVE-2019-12293 描述：Poppler是一個用于生成PDF的C++類庫，該庫是從Xpdf（PDF閱讀器）繼承而來。Poppler 0.76.1及之前版本中的JPEG2000Stream.cc文件的‘JPXStream：：init’函數(shù)存在越界讀取漏洞。該漏洞源于網(wǎng)絡(luò)系統(tǒng)或產(chǎn)品在內(nèi)存上執(zhí)行操作時，未正確驗證數(shù)據(jù)邊界，導(dǎo)致向關(guān)聯(lián)的其他內(nèi)存位置上執(zhí)行了錯誤的讀寫操作。攻擊者可利用該漏洞導(dǎo)致緩沖區(qū)溢出或堆溢出等。 ·CVE-2019-9959 描述：Poppler 0.78.0及更早版本中的JPXStream:：init函數(shù)不檢查流長度的負值，從而導(dǎo)致整數(shù)溢出，從而使得在堆上分配一個大內(nèi)存塊成為可能，其大小由攻擊者控制，如pdftocairo所示。 2.受影響的軟件包 ·中標麒麟高級服務(wù)器操作系統(tǒng) V7 ·aarch64架構(gòu):
