CVE-2017-16995

kernel: memory corruption caused by BPF verifier bugs can allow for arbitrary code execution

The check_alu_op function in kernel/bpf/verifier.c in the Linux kernel through 4.4 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging incorrect sign extension.

php: Out-of-bound read in timelib_meridian()

In PHP before 5.6.32, 7.x before 7.0.25, and 7.1.x before 7.1.11, an error in the date extension's timelib_meridian handling of 'front of' and 'back of' directives could be used by attackers able to supply date strings to leak information from the interpreter, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function. NOTE: this is a different issue than CVE-2017-11145.

vim: Sets the group ownership of a .swp file to the editor's primary group

fileio.c in Vim prior to 8.0.1263 sets the group ownership of a .swp file to the editor's primary group (which may be different from the group ownership of the original file), which allows local users to obtain sensitive information by leveraging an applicable group membership, as demonstrated by /etc/shadow owned by root:shadow mode 0640, but /etc/.shadow.swp owned by root:users mode 0640, a different vulnerability than CVE-2017-1000382.

rsync: Heap-based buffer over-read in receive_xattr function

The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon.

libXcursor: file.c: heap-based buffer overflow when reading/creating images

libXcursor before 1.1.15 has various integer overflows that could lead to heap buffer overflows when processing malicious cursors, e.g., with programs like GIMP. It is also possible that an attack vector exists against the related code in cursor/xcursor.c in Wayland through 1.14.0.

kernel: Salsa20 encryption algorithm does not correctly handle zero-length inputs allowing local attackers to cause denial-of-service

The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.

CVE-2017-2888

SDL: Integer overflow while creating a new RGB surface

An exploitable integer overflow vulnerability exists when creating a new RGB Surface in SDL 2.0.5. A specially crafted file can cause an integer overflow resulting in too little memory being allocated which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.

exiv2: Segmentation fault in TiffImageEntry::doWriteImage function

An issue was discovered in Exiv2 0.26. When the data structure of the structure ifd is incorrect, the program assigns pValue_ to 0x0, and the value of pValue() is 0x0. TiffImageEntry::doWriteImage will use the value of pValue() to cause a segmentation fault. To exploit this vulnerability, someone must open a crafted tiff file.

git: Mishandling layers of tree objects

Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of service (memory consumption) via a crafted repository, aka a Git bomb. This can also have an impact of disk consumption; however, an affected process typically would not survive its attempt to build the data structure in memory before writing to disk.
