<p>musl is an implementation of the C standard library built on top of the
|
|
|
|
|
|
Linux system call API, including interfaces defined in the base language
|
|
|
|
|
|
standard, POSIX, and widely agreed-upon extensions.

|
|
|
|
|
|
<p>A flaw in musl libc’s arch-specific math assembly code for i386 was
|
|
|
|
|
|
found which can lead to x87 stack overflow in the execution of subsequent
|
|
|
|
|
|
math code.

<impact type="normal">
|
|
|
|
|
|
<p>Impact depends on how the application built against musl libc handles
|
|
|
|
|
|
the ABI-violating x87 state.
