An x87 stack handling error in musl might allow an attacker to have an application dependent impact.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| sys-libs/musl | * | < 1.1.24 | >= 1.1.24 |
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.
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 depends on how the application built against musl libc handles the ABI-violating x87 state.
There is no known workaround at this time.
All musl users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/musl-1.1.24"
An integer overflow in musl might allow an attacker to execute arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| sys-libs/musl | * | < 1.1.15-r2 | >= 1.1.15-r2 |
musl is a “libc”, an implementation of the standard library functionality described in the ISO C and POSIX standards, plus common extensions, intended for use on Linux-based systems.
A vulnerability was discovered in musl’s tre_tnfa_run_parallel function buffer overflow logic, due to the incorrect use of integer types and missing overflow checks.
An attacker, who controls the regular expression and/or string being searched, could execute arbitrary code with the privileges of the process.
There is no known workaround at this time.
All musl users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/musl-1.1.15-r2"
