CVE-2015-2059: Buffer Overflow
First published: Wed Aug 12 2015(Updated: )
The stringprep_utf8_to_ucs4 function in libin before 1.31, as used in jabberd2, allows context-dependent attackers to read system memory and possibly have other unspecified impact via invalid UTF-8 characters in a string, which triggers an out-of-bounds read.
