CVE-ID : CVE-2017-15670 CVE-2017-15671
Package : lib32-glibc
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-460
The package lib32-glibc before version 2.26-9 is vulnerable to multiple
issues including arbitrary code execution and denial of service.
Upgrade to 2.26-9.
The problems have been fixed upstream but no release is available yet.
None.
The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-
one error leading to a heap-based buffer overflow in the glob function
in glob.c, related to the processing of home directories using the ~
operator followed by a long string.
The glob function in glob.c in the GNU C Library (aka glibc or libc6)
before 2.27, when invoked with GLOB_TILDE, could skip freeing allocated
memory when processing the ~ operator with a long user name,
potentially leading to a denial of service (memory leak).
A remote attacker is able to execute arbitrary code on the host or
crash a target application that is using glibc functions for globbing
by providing a crafted input to it.
