Description Adam Mariš 2015-12-22 09:23:29 UTC
Stack-based buffer overflow vulnerabilities were found in conv_jistoeuc, conv_euctojis, conv_sjistoeuc functions, caused by missing bound checking on the output buffer, which is created on the stack with alloca().

Comment 2 Michael Schwendt 2015-12-22 11:10:28 UTC
> Upstream patch:

Dubious. The change to conv_jistoeuc() disables the loop, because (out-outbuf) will be zero and hence the while-condition will never be true.

Apart from that, the patch is part of 3.13.1 which is pending on its way into updates-testing already.
