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. 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-2018-11237)

It was discovered that the GNU C Library incorrectly handled certain hostname loookups. 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-2018-19591)

Jakub Wilk discovered that the GNU C Library incorrectly handled certain memalign functions. 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-2018-6485)

It was discovered that the GNU C Library incorrectly ignored the LDPREFERMAP32BITEXEC environment variable after security transitions. A local attacker could use this issue to bypass ASLR restrictions. (CVE-2019-19126)

It was discovered that the GNU C Library incorrectly handled certain regular expressions. A remote attacker could possibly use this issue to cause the GNU C Library to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2019-9169)

It was discovered that the GNU C Library incorrectly handled certain bit patterns. 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 and Ubuntu 18.04 LTS. (CVE-2020-10029)

It was discovered that the GNU C Library incorrectly handled certain signal trampolines on PowerPC. 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. (CVE-2020-1751)

It was discovered that the GNU C Library incorrectly handled tilde expansion. 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. (CVE-2020-1752)
