Stack-based buffer overflow in the _nc_write_entry function in tinfo/write_entry.c in ncurses 6.0 allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted terminfo file, as demonstrated by tic.

Vulnerability in the Oracle Communications WebRTC Session Controller component of Oracle Communications Applications (subcomponent: Security (Gson)). Supported versions that are affected are 7.0, 7.1 and 7.2. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise Oracle Communications WebRTC Session Controller. While the vulnerability is in Oracle Communications WebRTC Session Controller, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Communications WebRTC Session Controller. CVSS 3.0 Base Score 6.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:N/A:H).

There is an illegal address access in the fmt_entry function in progs/dump_entry.c in ncurses 6.0 that might lead to a remote denial of service attack.

There is an illegal address access in the _nc_safe_strcat function in strings.c in ncurses 6.0 that will lead to a remote denial of service attack.

There is an illegal address access in the function postprocess_termcap() in parse_entry.c in ncurses 6.0 that will lead to a remote denial of service attack.

There is an illegal address access in the function dump_uses() in progs/dump_entry.c in ncurses 6.0 that might lead to a remote denial of service attack.

There is an illegal address access in the function _nc_read_entry_source() in progs/tic.c in ncurses 6.0 that might lead to a remote denial of service attack.

There is an infinite loop in the next_char function in comp_scan.c in ncurses 6.0, related to libtic. A crafted input will lead to a remote denial of service attack.

There is an illegal address access in the _nc_save_str function in alloc_entry.c in ncurses 6.0. It will lead to a remote denial of service attack.

Bad reference counting in the context of accept_ice_connection() in gsm-xsmp-server.c in old versions of gnome-session up until version 2.29.92 allows a local attacker to establish ICE connections to gnome-session with invalid authentication data (an invalid magic cookie). Each failed authentication attempt will leak a file descriptor in gnome-session. When the maximum number of file descriptors is exhausted in the gnome-session process, it will enter an infinite loop trying to communicate without success, consuming 100% of the CPU. The graphical session associated with the gnome-session process will stop working correctly, because communication with gnome-session is no longer possible.
