Summary
glibc vulnerabilities
Details

Jason Royes and Samuel Dytrych discovered that the memcpy() implementation for 32 bit ARM processors in the GNU C Library contained an integer underflow vulnerability. An attacker could possibly use this to cause a denial of service (application crash) or execute arbitrary code. (CVE-2020-6096)

It was discovered that the POSIX regex implementation in the GNU C Library did not properly parse alternatives. An attacker could use this to cause a denial of service. (CVE-2009-5155)
