The "insert-blank-characters" capability in caps.c in gnome-terminal (vte) before 0.28.1 allows remote authenticated users to cause a denial of service (CPU and memory consumption and crash) via a crafted file, as demonstrated by a file containing the string "\033[100000000000000000@".

The vte_sequence_handler_window_manipulation function in vteseq.c in libvte (aka libvte9) in VTE 0.25.1 and earlier, as used in gnome-terminal, does not properly handle escape sequences, which allows remote attackers to execute arbitrary commands or obtain potentially sensitive information via a (1) window title or (2) icon title sequence. NOTE: this issue exists because of a CVE-2003-0070 regression.
