|---|---|---|---|---|---|---|---|---|
| CVE-2021-26937 | Cri | 0.64 | 9.8 | 0.09 | Feb 9, 2021 | encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character sequence. | ||
| CVE-2020-9366 | Cri | 0.64 | 9.8 | 0.03 | Feb 24, 2020 | A buffer overflow was found in the way GNU Screen before 4.8.0 treated the special escape OSC 49. Specially crafted output, or a special program, could corrupt memory and crash Screen or possibly have unspecified other impact. | ||
| CVE-2017-5618 | Hig | 0.51 | 7.8 | 0.01 | Mar 20, 2017 | GNU screen before 4.5.1 allows local users to modify arbitrary files and consequently gain root privileges by leveraging improper checking of logfile permissions. | ||
| CVE-2023-24626 | Med | 0.45 | 6.5 | 0.01 | Apr 8, 2023 | socket.c in GNU Screen through 4.9.0, when installed setuid or setgid (the default on platforms such as Arch Linux and FreeBSD), allows local users to send a privileged SIGHUP signal to any PID, causing a denial of service or disruption of the target process. | ||
| CVE-2007-3048 | 0.03 | — | 0.01 | Jun 5, 2007 | GNU screen 4.0.3 allows local users to unlock the screen via a CTRL-C sequence at the password prompt. NOTE: multiple third parties report inability to reproduce this issue | |||
| CVE-2002-1602 | 0.03 | — | 0.01 | Apr 23, 2002 | Buffer overflow in the Braille module for GNU screen 3.9.11, when HAVE_BRAILLE is defined, allows local users to execute arbitrary code. | |||
| CVE-2015-6806 | 0.00 | — | 0.04 | Sep 28, 2015 | The MScrollV function in ansi.c in GNU screen 4.3.1 and earlier does not properly limit recursion, which allows remote attackers to cause a denial of service (stack consumption) via an escape sequence with a large repeat count value. | |||
| CVE-2009-1215 | 0.00 | — | 0.00 | Apr 1, 2009 | Race condition in GNU screen 4.0.3 allows local users to create or overwrite arbitrary files via a symlink attack on the /tmp/screen-exchange temporary file. | |||
| CVE-2009-1214 | 0.00 | — | 0.00 | Apr 1, 2009 | GNU screen 4.0.3 creates the /tmp/screen-exchange temporary file with world-readable permissions, which might allow local users to obtain sensitive session information. | |||
| CVE-2006-4573 | 0.00 | — | 0.02 | Oct 24, 2006 | Multiple unspecified vulnerabilities in the "utf8 combining characters handling" (utf8_handle_comb function in encoding.c) in screen before 4.0.3 allows user-assisted attackers to cause a denial of service (crash or hang) via certain UTF8 sequences. | |||
| CVE-2003-0972 | 0.00 | — | 0.03 | Dec 15, 2003 | Integer signedness error in ansi.c for GNU screen 4.0.1 and earlier, and 3.9.15 and earlier, allows local users to execute arbitrary code via a large number of ";" (semicolon) characters in escape sequences, which leads to a buffer overflow. | |||
| CVE-2000-0364 | 0.00 | — | 0.00 | Jun 1, 1999 | screen and rxvt in Red Hat Linux 6.0 do not properly set the modes of tty devices, which allows local users to write to other ttys. |
