<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">emacs security update</Note>
<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for emacs is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3,openEuler-22.03-LTS and openEuler-22.03-LTS-SP1.</Note>
<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Emacs is the extensible, customizable, self-documenting real-time display editor.At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. And it is an entire ecosystem of functionality beyond text editing,including a project planner, mail and news reader, debugger interface, calendar, and more.
Security Fix(es):
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)
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)
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 &quot;etags -u *&quot; 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>
<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for emacs is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3,openEuler-22.03-LTS and openEuler-22.03-LTS-SP1.
openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="3" xml:lang="en">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.</Note>
