  1. CVE-2021-3420

    Critical · CVSS 9.8EPSS 2.1%Fix available

    CVE-2021-3420

    A flaw was found in newlib in versions prior to 4.0.0. Improper overflow validation in the memory allocation functions mEMALIGn, pvALLOc, nano_memalign, nano_valloc, nano_pvalloc could case an integer overflow, leading to an allocation of a small buffer and then to a heap-based buffer overflow.

  2. CVE-2019-14876

    Medium · CVSS 6.5EPSS 1.49%Fix available

    CVE-2019-14876

    In the __lshift function of the newlib libc library, all versions prior to 3.3.0 (see newlib/libc/stdlib/mprec.c), Balloc is used to allocate a big integer, however no check is performed to verify if the allocation succeeded or not. The access to b1 will trigger a null pointer dereference bug in case of a memory allocation failure.

  3. CVE-2019-14875

    Medium · CVSS 6.5EPSS 1.29%Fix available

    CVE-2019-14875

    In the __multiply function of the newlib libc library, all versions prior to 3.3.0 (see newlib/libc/stdlib/mprec.c), Balloc is used to allocate a big integer, however no check is performed to verify if the allocation succeeded or not. The access of _x[0] will trigger a null pointer dereference bug in case of a memory allocation failure.

  4. CVE-2019-14874

    Medium · CVSS 6.5EPSS 1.49%Fix available

    CVE-2019-14874

    In the __i2b function of the newlib libc library, all versions prior to 3.3.0 (see newlib/libc/stdlib/mprec.c), Balloc is used to allocate a big integer, however no check is performed to verify if the allocation succeeded or not. The access of _ x[0] will trigger a null pointer dereference bug in case of a memory allocation failure.

  5. CVE-2019-14878

    Medium · CVSS 6.5EPSS 1.32%Fix available

    CVE-2019-14878

    In the __d2b function of the newlib libc library, all versions prior to 3.3.0 (see newlib/libc/stdlib/mprec.c), Balloc is used to allocate a big integer, however no check is performed to verify if the allocation succeeded or not. Accessing _x will trigger a null pointer dereference bug in case of a memory allocation failure.

  6. CVE-2019-14877

    Medium · CVSS 6.5EPSS 1.29%Fix available

    CVE-2019-14877

    In the __mdiff function of the newlib libc library, all versions prior to 3.3.0 (see newlib/libc/stdlib/mprec.c), Balloc is used to allocate big integers, however no check is performed to verify if the allocation succeeded or not. The access to _wds and _sign will trigger a null pointer dereference bug in case of a memory allocation failure.

  7. CVE-2019-14873

    Medium · CVSS 6.5EPSS 1.46%Fix available

    CVE-2019-14873

    In the __multadd function of the newlib libc library, prior to versions 3.3.0 (see newlib/libc/stdlib/mprec.c), Balloc is used to allocate a big integer, however no check is performed to verify if the allocation succeeded or not. This will trigger a null pointer dereference bug in case of a memory allocation failure.

  8. CVE-2019-14871

    Medium · CVSS 6.5EPSS 1.02%Fix available

    CVE-2019-14871

    The REENT_CHECK macro (see newlib/libc/include/sys/reent.h) as used by REENT_CHECK_TM, REENT_CHECK_MISC, REENT_CHECK_MP and other newlib macros in versions prior to 3.3.0, does not check for memory allocation problems when the DEBUG flag is unset (as is the case in production firmware builds).

  9. CVE-2015-2305

    Not ratedEPSS 8.88%Fix available

    CVE-2015-2305

    Integer overflow in the regcomp implementation in the Henry Spencer BSD regex library (aka rxspencer) alpha3.8.g5 on 32-bit platforms, as used in NetBSD through 6.1.5 and other products, might allow context-dependent attackers to execute arbitrary code via a large regular expression that leads to a heap-based buffer overflow.
