systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.

In CCN-lite 2, the Parser of NDNTLV does not verify whether a certain component’s length field matches the actual component length, which has a resultant buffer overflow and out-of-bounds memory accesses.

A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6.

An issue was discovered in GNU patch through 2.7.6. There is a segmentation fault, associated with a NULL pointer dereference, leading to a denial of service in the intuit_diff_type function in pch.c, aka a “mangled rename” issue.

In CCN-lite 2, the function ccnl_prefix_to_str_detailed can cause a buffer overflow, when writing a prefix to the buffer buf. The maximal size of the prefix is CCNL_MAX_PREFIX_SIZE; the buffer has the size CCNL_MAX_PREFIX_SIZE. However, when NFN is enabled, additional characters are written to the buffer (e.g., the “NFN” and “R2C” tags). Therefore, sending an NFN-R2C packet with a prefix of size CCNL_MAX_PREFIX_SIZE can cause an overflow of buf inside ccnl_prefix_to_str_detailed.

An uninitialised stack variable in the nxfuse component that is part of the Open Source DokanFS library shipped with NoMachine 6.0.66_2 and earlier allows a local low privileged user to gain elevation of privileges on Windows 7 (32 and 64bit), and denial of service for Windows 8 and 10.
