A flaw was found in the implementation of assert() in the GNU C Library, the C standard library implementation used by Debian. When the function fails, it does not allocate enough space for the assertion failure message string and size information, which may lead to a buffer overflow if the message string size aligns to page size.



For Debian 8 jessie, these problems have been fixed in version 2.19-18+deb8u15.

For Debian 9 stretch, these problems have been fixed in version 2.24-11+deb9u8.

We recommend that you upgrade your glibc packages.
