NewStart CGSL CORE 5.05 / MAIN 5.05 : curl Vulnerability (NS-SA-2019-0171)
Critical Nessus Plugin ID 128701
SynopsisThe remote machine is affected by a vulnerability.
DescriptionThe remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has curl packages installed that are affected by a vulnerability:
- 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)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade the vulnerable CGSL curl packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
