SUSE CVE-2026-8796

Sereal::Decoder versions before 5.005 for Perl allow heap out-of-bounds read via crafted input. In Perl/Decoder/srldecoder.c, srlreadobject and srlreadhash process a COPY tag, a back-reference whose target byte the decoder re-decodes as a fresh tag. When that target byte matches the SHORTBINARY...

CVE-2018-25432

Arm Whois 3.11 contains a buffer overflow vulnerability that allows local attackers to execute arbitrary code by overwriting the structured exception handler. Attackers can craft a malicious input file with a 672-byte offset to overwrite the nSEH and SEH pointers, enabling code execution through...

CVE-2018-25432

Arm Whois 3.11 is affected by a local buffer overflow that allows code execution via exception handler hijacking. An input file crafted with a 672-byte offset can overwrite nSEH and SEH pointers, enabling arbitrary code execution when the structured exception handler is triggered. CVSS data prese...

CVE-2026-46384 iskorotkov/avro: Integer Overflow in Avro Decoder

iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, several Avro decoder paths read attacker-controlled 64-bit values from the wire format and either narrowed them to platform-sized int before bounds-checking, or summed them with overflow-prone signed-int arithmetic. On 32-bit targets...

CVE-2026-41075

A flaw was found in RT, an open-source issue and ticket tracking system. An authenticated user can exploit an SQL injection vulnerability by crafting malicious input. This input is then incorporated into database queries without proper validation, potentially allowing the attacker to read or modi...
