Bug ID: 3244
Summary: ASAN found two memory leaks in sshd.c
Product: Portable OpenSSH
Version: -current
Hardware: Other
OS: Linux
Status: NEW
Severity: enhancement
Priority: P5
Component: sshd
Assignee: unassigned-bugs at mindrot.org
Reporter: filmil+mindrot at gmail.com
An ASAN build of openssh-portable found the following memory leaks in
sshd.c:
(1)
https://github.com/openssh/openssh-portable/blob/master/sshd.c#L249:
auth_opts is never freed.
(2)
https://github.com/openssh/openssh-portable/blob/master/sshd.c#L2363
compat_pkgalg_proposal yields ownership of the returned "char*", which
is never freed thereafter.
Not sure if y'all care about issues like these, so I wanted to check
first.
