CVE-2022-48337
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.62%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
