wireshark: Kafka protocol dissector could crash (wnpa-sec-2020-10)

In Wireshark 3.2.0 to 3.2.5, the Kafka protocol dissector could crash. This was addressed in epan/dissectors/packet-kafka.c by avoiding a double free during LZ4 decompression.

gnome-shell: Password from logged-out user may be shown on login screen

An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4. When logging out of an account, the password box from the login dialog reappears with the password still visible. If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.)

Firejail through 0.9.62 mishandles shell metacharacters during use of the --output or --output-stderr option, which may lead to command injection.

Firejail through 0.9.62 does not honor the -- end-of-options indicator after the --output option, which may lead to command injection.

scm/define-stencil-commands.scm in LilyPond through 2.20.0, and 2.21.x through 2.21.4, when -dsafe is used, lacks restrictions on embedded-ps and embedded-svg, as demonstrated by including dangerous PostScript code.

golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs

Go before 1.13.15 and 14.x before 1.14.7 can have an infinite read loop in ReadUvarint and ReadVarint in encoding/binary via invalid inputs.

kernel: information exposure in drivers/char/random.c and kernel/time/timer.c

The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.

In GNOME Balsa before 2.6.0, a malicious server operator or man in the middle can trigger a NULL pointer dereference and client crash by sending a PREAUTH response to imap_mbox_connect in libbalsa/imap/imap-handle.c.

ark: maliciously crafted archive can install files anywhere in the user's home directory

In kerfuffle/jobs.cpp in KDE Ark before 20.08.0, a crafted archive can install files outside the extraction directory via ../ directory traversal.

QEMU: reachable assertion failure in net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c

In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in hw/net/net_tx_pkt.c.
