1 CVE-2018-1000001 119 Exec Code Overflow 2018-01-31 2018-06-15
7.2
None Local Low Not required Complete Complete Complete
In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution.
2 CVE-2018-11237 119 Overflow 2018-05-18 2018-10-31
4.6
None Local Low Not required Partial Partial Partial
An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in __mempcpy_avx512_no_vzeroupper.
3 CVE-2018-11236 190 Exec Code Overflow 2018-05-18 2018-10-31
6.8
None Remote Medium Not required Partial Partial Partial
stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.
4 CVE-2018-6551 119 Overflow 2018-02-02 2018-02-22
7.5
None Remote Low Not required Partial Partial Partial
The malloc implementation in the GNU C Library (aka glibc or libc6), from version 2.24 to 2.26 on powerpc, and only in version 2.26 on i386, did not properly handle malloc calls with arguments close to SIZE_MAX and could return a pointer to a heap region that is smaller than requested, eventually leading to heap corruption.
5 CVE-2018-6485 190 Overflow 2018-02-01 2018-10-31
7.5
None Remote Low Not required Partial Partial Partial
An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption.
6 CVE-2017-1000409 119 Overflow 2018-01-31 2018-02-15
6.9
None Local Medium Not required Complete Complete Complete
A buffer overflow in glibc 2.5 (released on September 29, 2006) and can be triggered through the LD_LIBRARY_PATH environment variable. Please note that many versions of glibc are not vulnerable to this issue if patched for CVE-2017-1000366.
7 CVE-2017-18269 119 DoS Exec Code Overflow 2018-05-18 2018-06-20
7.5
None Remote Low Not required Partial Partial Partial
An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S in the GNU C Library (aka glibc or libc6) 2.21 through 2.27 does not correctly perform the overlapping memory check if the source memory range spans the middle of the address space, resulting in corrupt data being produced by the copy operation. This may disclose information to context-dependent attackers, or result in a denial of service, or, possibly, code execution.
