CVE-2026-45713 Mailpit: Unauthenticated remote memory-exhaustion DoS via unlimited SMTP DATA and /api/v1/send body sizes

Mailpit is an email testing tool and API for developers. Prior to version 1.30.0, the Mailpit SMTP server has a Server.MaxSize int field that controls the maximum allowed DATA payload size, but the field is never assigned anywhere outside test code, leaving it at Go's zero value 0 ⇒ "no limit". T...

CVE-2026-55392 NILFS utilities - Undefined Behavior and Out-of-Memory via Unvalidated s_log_block_size

NILFS utilities through 2.3.0, fixed in commit 26efb5d, nilfssbisvalid function fails to validate slogblocksize field in NILFS2 superblock before bit-shift operations. Attackers supplying crafted NILFS2 images trigger undefined behavior through oversized shifts or out-of-memory conditions, crashi...

CVE-2025-71329

A flaw was found in image-size. A remote attacker can exploit this vulnerability by providing a specially crafted image buffer that contains a zero-valued size field within a recognized box-type. This malicious input can trigger an infinite loop in the JXL or HEIF image parsers, leading to a...

CVE-2026-9538

A flaw was found in the perl-Archive-Tar component. An attacker can exploit this vulnerability by providing a crafted tar header with an excessively large entry size field. This can lead to memory exhaustion, resulting in a Denial of Service DoS for the affected system. Mitigation To mitigate thi...

CVE-2026-9538 Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header

Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. readtar reads each entry's payload with $handle-read$$data, $block, where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that...

CVE-2026-9538

CVE-2026-9538 affects Archive::Tar prior to 3.10 for Perl. A crafted tar header can set a multi‑gigabyte size, causing _read_tar() to allocate a scalar of that size, leading to memory exhaustion. The vulnerability arises from reading entry payloads with a size block derived from the header withou...
