Title:	Debian: Security Advisory (DLA-3257-1)
Summary:	The remote host is missing an update for the Debian 'emacs' package(s) announced via the DLA-3257-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'emacs' package(s) announced via the DLA-3257-1 advisory. Vulnerability Insight: 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. 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. 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.

Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
