Function Documentation

◆ write_safe_address()

static void write_safe_address ( FILE *  fp,
char *  s 
)
static

Defang malicious email addresses.

Parameters
fpFile to write to
sEmail address to defang

if someone has an address like From: Michael /bin/rm -f ~ Elkins me@mu.nosp@m.tt.o.nosp@m.rg and the user creates an alias for this, NeoMutt could wind up executing the backticks because it writes aliases like alias me Michael /bin/rm -f ~ Elkins me@mu.nosp@m.tt.o.nosp@m.rg To avoid this problem, use a backslash () to quote any backticks. We also need to quote backslashes as well, since you could defeat the above by doing From: Michael `/bin/rm -f ~` Elkins me@mu.nosp@m.tt.o.nosp@m.rg since that would get aliased as alias me Michael \`/bin/rm -f ~\` Elkins me@mu.nosp@m.tt.o.nosp@m.rg which still gets evaluated because the double backslash is not a quote.

Additionally, we need to quote ' and " characters - otherwise, neomutt will interpret them on the wrong parsing step.

$ wants to be quoted since it may indicate the start of an environment variable.
