Descriptions
A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.
It was discovered that GnuTLS incorrectly handled exporting Subject Alternative Name entries containing an otherName. A remote attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. It was discovered that the GnuTLS certtool utility incorrectly handled parsing certain template files. An attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code.
