CVE-ID : CVE-2017-10965 CVE-2017-10966
Package : irssi
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-342
The package irssi before version 1.0.4-1 is vulnerable to multiple
issues including arbitrary code execution and denial of service.
Upgrade to 1.0.4-1.
The problems have been fixed upstream in version 1.0.4.
None.
When receiving messages with invalid time stamps, Irssi would try to
dereference a NULL pointer. This requires control over the IRC server,
or a position of man-in-the-middle to be exploited.
While updating the internal nick list, Irssi may incorrectly use the
GHashTable interface and free the nick while updating it. This will
then result in use-after-free conditions on each access of the hash
table. Note that this should not happen with a conforming IRC server,
so it requires control over the IRC server or a position of man-in-the-
middle to be exploitable.
A remote attacker in position of man-in-the-middle or controlling the
IRC server might be able to crash or execute arbitrary code on an
affected host.
