Related Vulnerabilities: CVE-2017-10684   CVE-2017-10685   CVE-2017-11112   CVE-2017-13729   CVE-2017-13730   CVE-2017-13731   CVE-2017-13732   CVE-2017-13733   CVE-2017-13734   CVE-2017-11113   CVE-2017-13728  

Several security issues were fixed in ncurses.

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)

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)
