简介
远程 Debian 主机上缺少一个或多个与安全性相关的更新。描述
远程 Debian 11 主机上安装的程序包受到 dsa-4959 公告中提及的多个漏洞影响。- Mozilla 开发人员报告 Firefox 90 和 Firefox ESR 78.12 中存在内存安全错误。其中某些错误展示出内存损坏迹象，我们推测如果攻击者进行足够的尝试，则可以利用此漏洞运行任意代码。此漏洞会影响 Thunderbird < 78.13、Firefox ESR < 78.13 和 Firefox < 91。(CVE-2021-29989)
- 指令重新排序会导致一系列指令，造成程序在垃圾回收期间错误地考虑对象。这可能导致内存损坏和可能遭利用的程序崩溃。
此漏洞会影响 Thunderbird < 78.13、Thunderbird < 91、Firefox ESR < 78.13 和 Firefox < 91。
(CVE-2021-29984)
- 媒体通道中存在释放后使用漏洞，这可导致内存损坏和可能遭利用的程序崩溃。此漏洞会影响 Thunderbird < 78.13、Thunderbird < 91、Firefox ESR < 78.13 和 Firefox < 91。(CVE-2021-29985)
- 调用 getaddrinfo 时疑似会发生争用情形，进而导致内存损坏以及可能遭利用的程序崩溃。*注：此问题仅影响 Linux 操作系统。其他操作系统不会受到影响。此漏洞会影响 Thunderbird < 78.13、Thunderbird < 91、Firefox ESR < 78.13 和 Firefox < 91。
(CVE-2021-29986)
- Firefox 会错误地将内联 list-item 元素视为 block 元素，从而导致越界读取或内存损坏，并造成可能被利用的程序崩溃。此漏洞会影响 Thunderbird < 78.13、Thunderbird < 91、Firefox ESR < 78.13 和 Firefox < 91。(CVE-2021-29988)
请注意，Nessus 没有测试此问题，而仅依赖于应用程序自我报告的版本号。
