CVE-2026-63091 1 Proftpd 1 Proftpd 2026-07-21 6.5 Medium
ProFTPD before 1.3.9c and 1.3.10rc3 contains a signed integer overflow vulnerability in the mod_sftp module's SCP size-record parser that allows authenticated low-privilege attackers to bypass ASLR by sending a crafted file size value of UINT64_MAX, which results in a negative off_t value. Attackers can exploit the subsequent conversion to uint32_t, causing an approximately 4 GB requested read length and forcing the server to read beyond the end of the SSH channel data and write overread process memory into the uploaded file. In tested configurations, the disclosed data contains libc, libcrypto, and PIE pointers sufficient to derive their randomized base addresses, thereby bypassing ASLR and enabling reliable exploitation of memory corruption vulnerabilities in the same process.
CVE-2026-41521 1 Neutrinolabs 1 Xrdp 2026-07-21 8.2 High
xrdp is an open source RDP server. Versions 0.10.6 and prior contain an integer overflow vulnerability when processing screen update messages within the vnc-any connection mode. A malicious remote VNC server can send crafted image dimensions that cause an integer overflow during memory buffer size calculation, resulting in an undersized allocation. Subsequent processing of the incoming image data using the original oversized parameters leads to an out-of-bounds read. An unauthenticated remote attacker could exploit this flaw to disclose sensitive information from the heap memory or cause a denial of service (DoS) via a process crash. This issue has been fixed in version 0.10.6.1.
CVE-2026-55057 1 Microsoft 8 365 Apps, Office 2016, Office 2019 and 5 more 2026-07-20 5.5 Medium
Integer overflow or wraparound in Microsoft Office allows an unauthorized attacker to disclose information locally.
CVE-2026-33327 1 Libvips 1 Libvips 2026-07-20 N/A
libvips is a fast image processing library with low memory needs. The `vipsload` operation in versions before and including 8.18.0 could incorrectly determine image dimensions leading to an integer overflow and a subsequent heap-based buffer overflow. This has been patched in version 8.18.1.
CVE-2026-64089 1 Linux 1 Linux Kernel 2026-07-20 9.8 Critical
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix negative last_changeset_len batadv_piv_tt::last_changeset_len len was declared as s16, but the field is never intended to hold a negative value. When a value greater than 32767 is assigned, it wraps to a negative signed integer. In batadv_send_my_tt_response(), last_changeset_len is temporarily widened to s32. The incorrectly negative s16 value propagates into the s32, causing batadv_tt_prepare_tvlv_local_data() to allocate a full sized buffer but populates only a small portion of it with the collected changeset. All remaining bits are kept uninitialized. Using an u16 avoids this type confusion and ensures that no (negative) sign extension is performed in batadv_send_my_tt_response().
CVE-2026-34963 2 Barebox, Pengutronix 2 Barebox, Barebox 2026-07-18 8.4 High
barebox version prior to 2026.04.0 contains multiple memory-safety vulnerabilities in the EFI PE loader in efi/loader/pe.c where integer overflow in virtual image size computation using 32-bit arithmetic on section VirtualAddress and size values allows undersized heap allocation, and PE section loading logic fails to validate that PointerToRawData plus copied size remains within the PE file buffer. An attacker can supply a malicious EFI PE binary via TFTP, USB, SD card, or network boot to trigger heap buffer overflow or out-of-bounds read from heap memory, potentially achieving code execution in bootloader context.
CVE-2026-40469 2 Gnu, Redhat 2 Gawk, Hummingbird 2026-07-17 2.8 Low
Integer overflow vulnerability has been found in "builtin.c" program file of gawk (do_sub() routine). This issue could be used to overwrite gawk heap metadata and objects causing the program to crash. It affects 32-bit builds of gawk in versions 5.4.0 and below.
CVE-2026-59117 1 Microsoft 1 Terminal 2026-07-17 7.5 High
Integer overflow or wraparound in Windows Terminal allows an unauthorized attacker to execute code over a network.
CVE-2026-55026 1 Microsoft 11 365 Apps, Office 2016, Office 2019 and 8 more 2026-07-16 6.2 Medium
Integer overflow or wraparound in Microsoft Office allows an unauthorized attacker to disclose information locally.
CVE-2026-58384 2 Gnu, Redhat 2 Gimp, Enterprise Linux 2026-07-16 7.3 High
A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.
CVE-2026-14544 1 Redhat 1 Enterprise Linux 2026-07-16 9.8 Critical
A flaw was found in HPLIP (HP Linux Imaging and Printing Software). This vulnerability, an incomplete fix for CVE-2026-8631, may allow a remote attacker to escalate privileges or achieve arbitrary code execution. This can occur through an integer overflow in the hpcups processing path when handling specially crafted print data.
