Alpine: libcurl, multiple curl packages: security update to 7.61.1-r0

critical Tenable Cloud Security Plugin ID 423816

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal
 function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how
 large temporary storage area to allocate from the heap. The length value is then subsequently used to
 iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit
 size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31
 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the
 intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is
 almost identical to CVE-2017-8816.) (CVE-2018-14618)
