Package : chicken Version : 4.7.0-1+deb7u2 CVE ID : CVE-2017-6949 Debian Bug : 858057
It was found that CHICKEN did not sanitize the size argument when allocating SRFI-4 vectors, which could lead to segfaults or buffer overflows with some sizes.
For Debian 7 "Wheezy", these problems have been fixed in version 4.7.0-1+deb7u2.
We recommend that you upgrade your chicken packages.
