Package        : exuberant-ctags
Version        : 1:5.9~svn20110310-12+deb10u1
CVE ID         : CVE-2022-4515
Debian Bug     : 1026995

A flaw was found in the way the exubertant-ctags source code parser
handled the "-o" command-line option which specifies the tag
filename. A crafted tag filename specified in the command line or in
the configuration file could have resulted in arbitrary command
execution because the externalSortTags() in sort.c calls the
system(3) function in an unsafe way.

For Debian 10 buster, this problem has been fixed in version
1:5.9~svn20110310-12+deb10u1.

We recommend that you upgrade your exuberant-ctags packages.
