USN-5379-1: klibc vulnerabilities
It was discovered that klibc did not properly perform
some mathematical operations, leading to an integer overflow.
An attacker could possibly use this issue to cause a crash,
resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2021-31870)
It was discovered that klibc did not properly handled some
memory allocations on 64 bit systems. An attacker could
possibly use this issue to cause a crash, resulting in a
denial of service, or possibly execute arbitrary code.
(CVE-2021-31871)
It was discovered that klibc did not properly handled some file
sizes values on 32 bit systems. An attacker could possibly use
this issue to cause a crash, resulting in a denial of service,
or possibly execute arbitrary code. (CVE-2021-31872)
It was discovered that klibc did not properly handled some
memory allocations. An attacker could possibly use this issue
to cause a crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2021-31873)
