CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 0CVE-2023-2491 – emacs: Regression of CVE-2023-28617 fixes in the Red Hat Enterprise Linux
https://notcve.org/view.php?id=CVE-2023-2491
A flaw was found in the Emacs text editor. Processing a specially crafted org-mode code with the "org-babel-execute:latex" function in ob-latex.el can result in arbitrary command execution. This CVE exists because of a CVE-2023-28617 security regression for the emacs package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2. • https://access.redhat.com/errata/RHSA-2023:2626 https://access.redhat.com/errata/RHSA-2023:3104 https://access.redhat.com/security/cve/CVE-2023-2491 https://bugzilla.redhat.com/show_bug.cgi?id=2192873 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 7.3EPSS: 0%CPEs: 1EXPL: 0CVE-2022-48338 – emacs: local command injection in ruby-mode.el
https://notcve.org/view.php?id=CVE-2022-48338
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. • https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=9a3b08061feea14d6f37685ca1ab8801758bfd1c https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FLPQ4K6H2S5TY3L5UDN4K4B3L5RQJYQ6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/U6HDBUQNAH2WL4MHWCTUZLN7NGF7CHTK https://www.debian.org/security/2023/dsa-5360 https://access.redhat.com/security/cve/CVE-2022-48338 https://bugzilla.redhat.com/show_bug.cgi?id=2171988 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •

https://notcve.org/view.php?id=CVE-2022-48339
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. A flaw was found in the Emacs package. If a file name or directory name contains shell metacharacters, arbitrary code may be executed. • https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=1b4dc4691c1f87fc970fbe568b43869a15ad0d4c https://lists.debian.org/debian-lts-announce/2023/05/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FLPQ4K6H2S5TY3L5UDN4K4B3L5RQJYQ6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/U6HDBUQNAH2WL4MHWCTUZLN7NGF7CHTK https://www.debian.org/security/2023/dsa-5360 https://access.redhat.com/security/cve/CVE-2022-48339 https://bugzill • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-116: Improper Encoding or Escaping of Output •

https://notcve.org/view.php?id=CVE-2022-48337
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. A flaw was found in the Emacs package. This flaw allows attackers to execute commands via shell metacharacters in the name of a source-code file. • https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=01a4035c869b91c153af9a9132c87adb7669ea1c https://lists.debian.org/debian-lts-announce/2023/05/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FLPQ4K6H2S5TY3L5UDN4K4B3L5RQJYQ6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/U6HDBUQNAH2WL4MHWCTUZLN7NGF7CHTK https://www.debian.org/security/2023/dsa-5360 https://access.redhat.com/security/cve/CVE-2022-48337 https://bugzill • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

https://notcve.org/view.php?id=CVE-2022-45939
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 ctags program. For example, a victim may use the "ctags *" command (suggested in the ctags documentation) in a situation where the current working directory has contents that depend on untrusted input. GNU Emacs hasta la versión 28.2 permite a los atacantes ejecutar comandos a través de metacaracteres de shell en el nombre de un archivo de código fuente, porque lib-src/etags.c utiliza la función de librería C del sistema en su implementación del programa ctags. Por ejemplo, una víctima puede utilizar el comando "ctags *" (sugerido en la documentación de ctags) en una situación en la que el directorio de trabajo actual tiene contenidos que dependen de entradas que no son de confianza. A flaw was found in Etags, the Ctags implementation of Emacs. • https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=d48bb4874bc6cd3e69c7a15fc3c91cc141025c51 https://lists.debian.org/debian-lts-announce/2022/12/msg00046.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FOSK3J7BBAEI4IITW2DRUKLQYUZYKH6Y https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GOXIH2FDEQJEAARE52C3GHTLGQFBYPIB https://www.debian.org/security/2023/dsa-5314 https://access.redhat.com/security/cve/CVE-2022-45939 https://bugzill • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
