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.
