Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-7083 advisory.

- 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)

- 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
