GHSA-35W3-PJM6-WJ95 Oj: Heap Buffer Overflow in Oj.dump Exception Serialization via Large Indent

Summary Oj.dump in object mode is vulnerable to a heap buffer overflow when serializing Exception objects with a large :indent value. The serializer allocates a buffer sized for the object's attributes but does not account for the indent bytes added on each write. With indent: 5000, the...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the fillindent function when serializing Exception objects with a large indentation value. An attacker can corrupt adjacent heap memory and potentially execute arbitrary code or cause a crash by supplying...

GHSA-3M6Q-JJ5J-38C9 Oj: Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Details Two-step chain in ext/oj/fast.c: 1. doceachchild line 1501 increments doc-where pas...

GHSA-3V45-F3VH-WG7M Oj: Stack Buffer Overflow in Oj.dump via Large Indent

Summary Oj.dump is vulnerable to a stack-based buffer overflow when a large :indent value is provided by the developer. fillindent in dump.h calls memsetindentstr, ' ', sizetopts-indent without validating the size. When opts-indent is set to INTMAX 2,147,483,647, the sizet cast preserves the larg...

CVE-2026-48773 ProxySQL pre-auth heap overflow in MySQL and PostgreSQL first-packet handling

ProxySQL is a proxy for MySQL and its forks, as well as PostgreSQL. Versions 2.0.18 through 3.0.8 have a pre-authentication heap memory corruption vulnerability in the MySQL and PostgreSQL protocol first-read paths. A remote unauthenticated client can declare an oversized first packet length, and...

CVE-2026-48773

Summary of CVE-2026-48773 : ProxySQL (versions 2.0.18–3.0.8) contains a pre-authentication heap memory corruption in the MySQL/PostgreSQL protocol first-read paths. A remote, unauthenticated client can declare an oversized first packet length, and ProxySQL passes that attacker-controlled length t...

CVE-2026-48715

radvd is a router advertisement daemon for IPv6. Prior to version 2.21, the radvdump utility shipped with radvd contains a stack buffer overflow in the Route Information option parser. When processing a crafted ICMPv6 Router Advertisement, printff copies up to 2032 bytes from attacker-controlled...

CVE-2026-48715

CVE-2026-48715 affects the radvddump utility shipped with radvd (prior to v2.21). The issue is a stack buffer overflow in the Route Information option parser: during processing of a crafted ICMPv6 Router Advertisement, print_ff() copies up to 2032 bytes from packet data into a 16-byte on-stack st...

CVE-2026-56208

A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing LAP mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when glaginframes is set to 1 or higher. This results in a 232-byte...

CVE-2026-3195

A flaw was found in QEMU. When reading input audio in the virtio-snd device input callback, the virtiosndpcmincb function did not check whether the iov could fit the data buffer, potentially leading to a heap out-of-bounds write. This issue exists due to an incomplete fix for CVE-2024-7730...
