SynopsisThe remote Debian host is missing one or more security-related updates.
DescriptionThe remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5360 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. In ruby-mode.el, the ruby-find-library-file function has a local command injection vulnerability. The ruby-find-library-file function is an interactive function, and bound to C-c C-f. Inside the function, the external command gem is called through shell- command-to-string, but the feature-name parameters are not escaped. Thus, malicious Ruby source files may cause commands to be executed. (CVE-2022-48338)
- 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)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade the emacs packages.
For the stable distribution (bullseye), these problems have been fixed in version 1
