CVE-2019-9169: Buffer Overflow

First published: Tue Feb 26 2019(Updated: )

GNU glibc is vulnerable to a heap-based buffer overflow, caused by a buffer over-read flaw in the proceed_next_node function in posix/regexec.c. By sending a specially-crafted argument using a case-insensitive regular-expression match, a remote attacker could overflow a buffer and execute arbitrary code on the system.
