CVE-2015-8708 [HIGH] CVE-2015-8708 claws-mail: Stack overflow in conv_euctojis()
CVE-2015-8708 claws-mail: Stack overflow in conv_euctojis()
A stack-based buffer overflow has been found in conv_euctojis() after applying incomplete patch for CVE-2015-8614. In conv_euctojis() the comparison is with outlen - 3, but each pass through the loop uses up to 5 bytes and the rest of the function may add another 4 bytes. The comparison should presumably be '<= outlen - 9' or equivalently '< outlen - 8'.

CVE-2015-8614 claws-mail: Stack overflow in conv_{jistoeuc,euctojis,sjistoeuc}
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().

> 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 3.1
