Illustrator versions 29.8.6, 30.3 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2026-41326 1 Katacontainers 1 Kata-containers 2026-05-13 8.8 High
Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. From v3.4.0 to v3.28.0, an oversight in the CopyFile policy (and perhaps the CopyFile handler) allows untrusted hosts to write to arbitrary locations inside the guest workload image. This can be used to overwrite binaries inside the guest and exfiltrate data from containers; even those running inside CVMs. This vulnerability is fixed in v3.29.0.
CVE-2025-65085 1 Ashlar 5 Argon, Cobalt, Cobalt Share and 2 more 2026-05-12 9.8 Critical
A Heap-based Buffer Overflow vulnerability is present in Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions 12.6.1204.216 and prior that could allow an attacker to disclose information or execute arbitrary code.
CVE-2026-6356 1 Augmentt 1 Augmentt 2026-05-12 9.6 Critical
A vulnerability in the web application allows standard users to escalate their privileges to those of a super administrator through parameter manipulation, enabling them to access and modify sensitive information.

CVE-2026-45130 1 Vim 1 Vim 2026-05-12 6.6 Medium
Vim is an open source, command line text editor. Prior to version 9.2.0450, a heap buffer overflow exists in read_compound() in src/spellfile.c when loading a crafted spell file (.spl) with UTF-8 encoding active. An attacker-controlled length field in the spell file's compound section overflows a 32-bit signed integer multiplication, causing a small buffer to be allocated for a write loop that runs many iterations, overflowing the heap. Because the 'spelllang' option can be set from a modeline, a text file modeline can trigger spell file loading if a malicious .spl file has been planted on the runtimepath. This issue has been patched in version 9.2.0450.
CVE-2026-42309 2 Python, Python-pillow 2 Pillow, Pillow 2026-05-12 5.5 Medium
Pillow is a Python imaging library. From version 11.2.1 to before version 12.2.0, passing nested lists as coordinates to APIs that accept coordinates such as ImagePath.Path, ImageDraw.ImageDraw.polygon and ImageDraw.ImageDraw.line could cause a heap buffer overflow, as nested lists were recursively unpacked beyond the allocated buffer. Coordinate lists are now validated to contain exactly two numeric coordinates. This issue has been patched in version 12.2.0.
CVE-2023-4911 7 Canonical, Debian, Fedoraproject and 4 more 51 Ubuntu Linux, Debian Linux, Fedora and 48 more 2026-05-12 7.8 High
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2025-12659 1 Siemens 1 Simcenter Femap 2026-05-12 N/A
The affected applications contains a memory corruption vulnerability while parsing specially crafted IPT files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-27349, ZDI-CAN-27389)
CVE-2026-4892 1 Dnsmasq 1 Dnsmasq 2026-05-12 8.4 High
A heap-based out-of-bounds write vulnerability in the DHCPv6 implementation of dnsmasq allows local attackers to execute arbitrary code with root privileges via a crafted DHCPv6 packet.
CVE-2026-41509 2 Cross-crypto, Cross-signature 2 Cross-implementation, Cross-implementation 2026-05-12 9.8 Critical
CROSS implementation contains reference and optimized implementations of the CROSS post-quantum signature algorithm. Prior to commit fc6b7e7, there is a buffer overflow in crypto_sign_open() caused by an underflow of the integer mlen. This issue has been patched via commit fc6b7e7.
CVE-2025-7545 1 Gnu 1 Binutils 2026-05-12 5.3 Medium
A vulnerability classified as problematic was found in GNU Binutils 2.45. Affected by this vulnerability is the function copy_section of the file binutils/objcopy.c. The manipulation leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The patch is named 08c3cbe5926e4d355b5cb70bbec2b1eeb40c2944. It is recommended to apply a patch to fix this issue.
CVE-2026-42046 1 Cacalabs 1 Libcaca 2026-05-12 7.8 High
libcaca is a colour ASCII art library. In 0.99.beta20 and earlier, an integer overflow vulnerability in libcaca's canvas import functionality allows an attacker to cause a controlled heap out-of-bounds write (heap overflow) by supplying a crafted file in the "caca" format. Depending on the build configuration and memory allocator, this may lead to memory corruption or remote code execution. This is the same vulnerability as CVE-2021-3410 but the fix at that time was not fully correct. Commit fb77acff9ba6bb01d53940da34fb10f20b156a23 fixes this vulnerability.
CVE-2025-11495 1 Gnu 1 Binutils 2026-05-12 3.3 Low
A vulnerability was determined in GNU Binutils 2.45. The affected element is the function elf_x86_64_relocate_section of the file elf64-x86-64.c of the component Linker. This manipulation causes heap-based buffer overflow. The attack can only be executed locally. The exploit has been publicly disclosed and may be utilized. Patch name: 6b21c8b2ecfef5c95142cbc2c32f185cb1c26ab0. To fix this issue, it is recommended to deploy a patch.
