Описание
Buffer Overflow vulnerability in postprocess_terminfo function in tinfo/parse_entry.c:997 in ncurses 6.1 allows remote attackers to cause a denial of service via crafted command.
A flaw has been identified in the ncurses library. This issue occurs when processing a crafted terminfo database, causing a heap-based buffer overflow, resulting in an application crash.
Отчет
Red Hat Product Security has rated this issue as having a Low security impact because processing terminfo descriptions in the source form should be handled the same way as executable files or source code of any programming language. Users are not supposed to use untrusted terminfo descriptions. The ncurses library shipped with Red Hat Enterprise Linux 9 is not affected by this vulnerability because it has a newer, fixed ncurses version.
Меры по смягчению последствий
Do not compile or decompile untrusted terminfo descriptions.
