Description Vasyl Kaigorodov 2015-01-13 09:52:56 UTC

Buffer overflow vulnerability has been reported [1] in CHICKEN Scheme's substring-index[-ci] procedures. This overrun is only triggered when an integer greater than zero is passed as the optional START argument. As a work-around users are advised to switch to the equivalent string-contains procedure from SRFI 13 which is also shipped with CHICKEN.

All releases of CHICKEN up until 4.9.0.1 are affected.

The issue is fixed by the patch at
http://lists.nongnu.org/archive/html/chicken-hackers/2014-12/txt2UqAS9CtvH.txt. This
fix will be included in the upcoming release versions 4.9.0.2, 4.9.1, 4.10.0, and 5.0.
