CVE-2026-49494

Comodo Internet Security's firewall driver Inspect.sys contains an integer underflow in its IPv6 packet parser. The parser decrements an unsigned 64-bit payload-length value taken from the IPv6 fixed header's payload length field by the size of each IPv6 extension header without validating it, so...

USN-8401-1: Netty vulnerabilities

It was discovered that Netty's HTTP proxy handler did not properly validate headers when constructing CONNECT requests. An attacker could possibly use this issue to inject arbitrary HTTP headers into CONNECT requests. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS,...

USN-8395-1 netatalk vulnerabilities

Arjun Basnet discovered that Netatalk incorrectly sanitized user input in its MySQL CNID backend. A remote authenticated attacker could possibly use this issue to conduct SQL injection attacks. CVE-2026-44047 Arjun Basnet discovered that Netatalk incorrectly handled UCS-2 character set conversion...

serialize-javascript: serialize-javascript: Denial of Service via specially crafted array-like object serialization

A flaw was found in serialize-javascript. An attacker can exploit this vulnerability by providing a specially crafted "array-like" object with an excessively large length property during the serialization process. This action causes the application to enter an intensive loop, leading to 100% CPU...

MariaDB: Stack Buffer Overflow in mariadb-dump quote_name() Allows Malicious Server to Execute Arbitrary Code on Client

A stack buffer overflow was discovered in the quotename function of the mariadb-dump client application. The overflow occurred due to a lack of length validation on table names returned by a malicious MySQL server. This allowed a server to provide an excessively long table name that would overflo...

When decoding a PP2 TYPE SSL TLV, HAProxyMessage.readNextTLV first calls header.retainedSliceheader.readerIndex, length and only then reads the 1-byte client field and 4-byte verify field. If the attacker sets the TLV length below 5, the subsequent readByte/readInt throws IndexOutOfBoundsExceptio...

SslClientHelloHandler.decode reads the 24-bit TLS handshake length and, when the ClientHello does not fit in the first record, eagerly allocates ctx.alloc.bufferhandshakeLength line 161. The guard at line 140 is handshakeLength maxClientHelloLength && maxClientHelloLength != 0, and the...

Amazon Linux 2023 : containerd, containerd-stress (ALAS2023-2026-1784)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1784 advisory. An authenticated SSH client that repeatedly opened channels which were rejected by the server caused unbounded memory growth, eventually crashing the server process and affecting all connected...

DoS vulnerability in HTTP/1.x chunked encoding parser triggered by maliciously crafted chunk lengths

When using the affected versions of the vibeio-http crate, an attacker could craft a malicious HTTP/1.x request with a large chunk length between usize::MAX - 1 and usize::MAX inclusive and send it, causing the server to crash integer overflow panic in debug builds, splitto out of bounds panic in...

SUSE CVE-2026-50256

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...
