Synopsis
The remote Debian host is missing one or more security-related updates.Description
The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3416 advisory.- GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the etags program. For example, a victim may use the etags -u * command (suggested in the etags documentation) in a situation where the current working directory has contents that depend on untrusted input. (CVE-2022-48337)
- An issue was discovered in GNU Emacs through 28.2. htmlfontify.el has a command injection vulnerability.
In the hfy-istext-command function, the parameter file and parameter srcdir come from external input, and parameters are not escaped. If a file name or directory name contains shell metacharacters, code may be executed. (CVE-2022-48339)
- org-babel-execute:latex in ob-latex.el in Org Mode through 9.6.1 for GNU Emacs allows attackers to execute arbitrary commands via a file name or directory name that contains shell metacharacters. (CVE-2023-28617)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade the emacs packages.For Debian 10 buster, these problems have been fixed in version 1
