postgresql: PostgreSQL: Arbitrary code execution via plperl tied hash heap buffer overflow

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the plperl component when returning a tied hash. This allows a function owner to execute arbitrary code as the operating system user running the database by providing a specially crafted function body. This could lead ...

postgresql: PostgreSQL: Arbitrary code execution via heap buffer overflow in regexp

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the regexp component, which can be triggered by a query author providing text that does not pass encoding validation. This can lead to unanticipated data growth, allowing the attacker to execute arbitrary code as the...

postgresql: PostgreSQL pg_dump: Arbitrary code execution via crafted transform lists

A flaw was found in PostgreSQL pgdump. A heap buffer overflow vulnerability exists when processing long function transform lists. An authenticated object creator can exploit this by providing a specially crafted transform list. This allows the attacker to execute arbitrary code as the operating...

postgresql: PostgreSQL: Arbitrary code execution via long POSIX timezone abbreviation

A heap buffer overflow flaw was found in the PostgreSQL tochartimestamptz function. An attacker can exploit this by supplying an overly long POSIX timezone abbreviation to execute arbitrary code as the database's operating system user, potentially resulting in complete system compromise...

Important: Red Hat Security Advisory: postgresql:16 security update

An update for the postgresql:16 module is now available for Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severi...

CVE-2026-88832

The BusyBox utility is vulnerable to a heap buffer overflow during romfs volume ID parsing . The root cause is the use of an unbounded strlen on attacker-controlled metadata, which leads to an unbounded memcpy into a fixed-size label buffer when processing crafted filesystem images. Practical con...

CVE-2026-88832

BusyBox romfs volume ID parsing uses unbounded strlen on attacker-controlled metadata, causing a heap buffer overflow when processing crafted filesystem images. Mitigation Avoid processing untrusted filesystem images with BusyBox blkid or findfs. Use the util-linux versions of these utilities...

CVE-2026-88830

A unit confusion in BusyBox TLS Montgomery reduction buffer allocation causes a pre-authentication heap buffer overflow when processing a crafted ClientKeyExchange message. Mitigation Do not use the BusyBox sslserver applet in production environments. Use a well-maintained TLS implementation such...

SUSE CVE-2026-83601

Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized DIMENSION SLOT value that str2ullencoded passes to pluginsdrrddimputtoslot in src/plugins.d/pluginsdinternals.h without an upper bound. prdarraycreate in...

vim: Vim: Heap buffer overflow allows arbitrary code execution

A heap buffer overflow in Vim allows a local attacker to cause a denial of service or potentially execute arbitrary code. The flaw is triggered by processing a specially crafted spell file, where the setsofo function fails to reset internal data between sections, leading to an out-of-bounds write...
