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)
