Subject: give each ctl it's own copy of password
|
|
Git-repo: https://gitlab.com/fetchmail/fetchmail.git
|
|
Git-commit: 469b0a212e7f047ab16ef46a9158df5fb373e8c2
|
|
|
|
pwdb_* and passwordfile options may free and re-allocate password
|
|
for each poll operation. Giving each context it's own copy of
|
|
the password should prevent accessing freed memory in another copy.
|
|
|
|
I haven't tested pwmd, but these seem like obvious fixes.
