SynopsisThe remote machine is affected by multiple vulnerabilities.
DescriptionThe remote NewStart CGSL host, running version MAIN 4.05, has glibc packages installed that are affected by multiple vulnerabilities:
- An integer overflow vulnerability was found in hcreate() and hcreate_r() functions which could result in an out- of-bounds memory access. This could lead to application crash or, potentially, arbitrary code execution.
- A stack based buffer overflow vulnerability was found in the catopen() function. An excessively long string passed to the function could cause it to crash or, potentially, execute arbitrary code. (CVE-2015-8779)
- A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap (or different memory region) and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is glibc-side mitigation which blocks processing of LD_LIBRARY_PATH for programs running in secure-execution mode and reduces the number of allocations performed by the processing of LD_AUDIT, LD_PRELOAD, and LD_HWCAP_MASK, making successful exploitation of this issue more difficult.
- It was found that out-of-range time values passed to the strftime() function could result in an out-of-bounds memory access. This could lead to application crash or, potentially, information disclosure. (CVE-2015-8776)
- A stack overflow vulnerability was found in nan* functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code. (CVE-2014-9761)
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 glibc packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
