In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses alternatives, which allows attackers to cause a denial of service (assertion failure and application exit) or trigger an incorrect result by attempting a regular-expression match.

CVE-2009-5155 [HIGH] GNU C Library vulnerabilities
Title: GNU C Library vulnerabilities
Summary: Several security issues were fixed in GNU C Library.
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)
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.
