 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3257-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb December 31, 2022 https://wiki.debian.org/LTS

 Package : emacs Version : 1:26.1+1-3.2+deb10u3 CVE ID : CVE-2022-45939 Debian Bug : 1025009

 It was discovered that there was an issue in Emacs where where attackers could have executed arbitrary commands via shell metacharacters in the name of a source-code file.

 This was because lib-src/etags.c used the system(3) library function when calling the (external) ctags(1) binary.

 For Debian 10 buster, this problem has been fixed in version 1:26.1+1-3.2+deb10u3.

 We recommend that you upgrade your emacs packages.

 For the detailed security status of emacs please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/emacs

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

Solution

Upgrade the emacs packages.
