kernel: Improper logic pruning in bpf/verifier.c

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service.

ReadOneJNGImage in coders/png.c in GraphicsMagick 1.3.26 has a use-after-free issue when the height or width is zero, related to ReadJNGImage.

sox: Heap-based buffer overflow in the ImaExpandS function

There is a heap-based buffer overflow in the ImaExpandS function of ima_rw.c in Sound eXchange (SoX) 14.4.2. A Crafted input will lead to a denial of service attack during conversion of an audio file.

sox: Reachable assertion abort in the function sox_append_comment()

There is a reachable assertion abort in the function sox_append_comment() in formats.c in Sound eXchange (SoX) 14.4.2. A Crafted input will lead to a denial of service attack during conversion of an audio file.

sox: Stack-based buffer overflow in the lsx_ms_adpcm_block_expand_i function

There is a stack-based buffer overflow in the lsx_ms_adpcm_block_expand_i function of adpcm.c in Sound eXchange (SoX) 14.4.2. A Crafted input will lead to a denial of service attack during conversion of an audio file.

kernel: bpf/verifier.c allows local users to cause a denial of service by leveraging mishandling of invalid variable stack read operations

The check_stack_boundary function in kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging mishandling of invalid variable stack read operations.

kernel: bpf/verifier.c allows local users to cause a denial of service by leveraging the lack of stack-pointer alignment enforcement

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the lack of stack-pointer alignment enforcement.

kernel: bpf/verifier.c allows local users to cause a denial of service by leveraging improper use of pointers in place of scalars

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging improper use of pointers in place of scalars.

kernel: bpf/verifier.c allows local users to cause a denial of service by leveraging unrestricted integer values for pointer arithmetic

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service (integer overflow and memory corruption) or possibly have unspecified other impact by leveraging unrestricted integer values for pointer arithmetic.

An issue was discovered in Enigmail before 1.9.9. Regular expressions are exploitable for Denial of Service, because of attempts to match arbitrarily long strings, aka TBE-01-003.

An issue was discovered in Enigmail before 1.9.9. Improper Random Secret Generation occurs because Math.Random() is used by pretty Easy privacy (pEp), aka TBE-01-001.

An issue was discovered in Enigmail before 1.9.9. A remote attacker can obtain cleartext content by sending an encrypted data block (that the attacker cannot directly decrypt) to a victim, and relying on the victim to automatically decrypt that block and then send it back to the attacker as quoted text, aka the TBE-01-005 "replay" issue.

An issue was discovered in Enigmail before 1.9.9 that allows remote attackers to trigger use of an intended public key for encryption, because incorrect regular expressions are used for extraction of an e-mail address from a comma-separated list, as demonstrated by a modified Full Name field and a homograph attack, aka TBE-01-002.

kernel: HMAC implementation does not validate that the underlying cryptographic hash algorithm is unkeyed allowing local attackers to cause denial-of-service

The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.

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.

gimp: Heap-based buffer over-read in ReadImage function in plug-ins/common/file-tga.c

In GIMP 2.8.22, there is a heap-based buffer over-read in ReadImage in plug-ins/common/file-tga.c (related to bgr2rgb.part.1) via an unexpected bits-per-pixel value for an RGBA image.
