Summary
ncurses vulnerabilities
Details
It was discovered that ncurses was not properly checking array bounds when executing the fmt_entry function, which could result in an out-of-bounds write. An attacker could possibly use this issue to execute arbitrary code. (CVE-2017-10684)
It was discovered that ncurses was not properly checking user input, which could result in it being treated as a format argument. An attacker could possibly use this issue to expose sensitive information or to execute arbitrary code. (CVE-2017-10685)
It was discovered that ncurses was incorrectly performing memory management operations and was not blocking access attempts to illegal memory locations. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-11112, CVE-2017-13729, CVE-2017-13730, CVE-2017-13731, CVE-2017-13732, CVE-2017-13733, CVE-2017-13734)
It was discovered that ncurses was not properly performing checks on pointer values before attempting to access the related memory locations, which could lead to NULL pointer dereferencing. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-11113)
It was discovered that ncurses was incorrectly handling loops in libtic, which could lead to the execution of an infinite loop. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-13728)
