Summary

glibc vulnerabilities

Details

Florian Weimer discovered that the GNU C Library incorrectly handled certain memory operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-12133)

It was discovered that the GNU C Library incorrectly handled certain SSE2-optimized memmove operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-18269)

It was discovered that the GNU C Library incorrectly handled certain pathname operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-11236)

It was discovered that the GNU C Library incorrectly handled certain AVX-512-optimized mempcpy operations.
