尽管安装了修复程序,debsecan 仍报告易受攻击的软件包

我有一个最新的 debian stable (bullseye) 安装,包括debian-security

$ cat /etc/apt/sources.list
deb http://deb.debian.org/debian/              bullseye          main contrib non-free
deb http://security.debian.org/debian-security bullseye-security main contrib non-free
deb http://deb.debian.org/debian/              bullseye-updates  main contrib non-free

deb-src http://deb.debian.org/debian/               bullseye          main contrib non-free
deb-src http://security.debian.org/debian-security/ bullseye-security main contrib non-free
deb-src http://deb.debian.org/debian/               bullseye-updates  main contrib non-free

当我运行时,我很惊讶地看到如此多的 CVE 被修复debsecan

$ debsecan --suite bullseye --only-fixed | wc -l
310

我查看了一些软件包,发现我已经安装了固定版本。在这种情况下,libc-bin 2.31-13+deb11u4似乎已修复 CVE-2021-33574。我已经+deb11u5安装了,所以我不明白为什么这个 CVE 在我的系统上被标记。

$ debsecan --suite bullseye --only-fixed --format detail
CVE-2021-33574 (fixed)
  The mq_notify function in the GNU C Library (aka glibc) versions 2.32  ...
  installed: libc-bin 2.31-13+deb11u5
             (built from glibc 2.31-13+deb11u5)
  fixed in unstable: glibc 2.32-1 (source package)
  fixed on branch:   glibc 2.28-10+deb10u2 (source package)
  fixed on branch:   glibc 2.31-13+deb11u3 (source package)
  fixed on branch:   glibc 2.31-13+deb11u4 (source package)
  fixed on branch:   glibc 2.32-0experimental0 (source package)
  fix is available for the selected suite (bullseye)

这是误报,还是我对这些结果的解释错误?

这个问题不仅仅适用于固定包。在这种情况下,我已安装,但xxd已修复。在这种情况下,修复是否会应用于,并同时跳过?8.1.0875-5+deb10u48.2.2434-3+deb11u1unstabletestingoldstablestable
