Amazon Linux 2023 Security Advisory: ALAS-2023-023
Advisory Release Date: 2023-02-17 20:43 Pacific
Advisory Updated Date: 2023-02-22 23:54 Pacific
Severity:
Medium
Issue Overview:
The ncurses package (tic) is susceptible to a heap overflow on crafted input. When the terminfo entry-description compiler processes input, proper bounds checking was not enforced leading to this software flaw. The highest threat from this vulnerability is system availability. (CVE-2021-39537)
A segmentation fault vulnerability was found in ncurses's convert_strings() function of tinfo/read_entry.c file. This flaw occurs due to corrupted terminfo data, triggering an out-of-bounds read error. (CVE-2022-29458)
Affected Packages:
