CVE-2016-4579 [HIGH] CVE-2016-4579 libksba: Out-of-bounds read in _ksba_ber_parse_tl
CVE-2016-4579 libksba: Out-of-bounds read in _ksba_ber_parse_tl
A vulnerability was found in libksba. The returned length of the object from _ksba_ber_parse_tl (ti.length) was not always checked against the actual buffer length, thus leading to a read access after the end of the buffer and a crash.
