CVE-2026-62433

The CVE-2026-62433 issue relates to the Xen DM_OP handling path. Connected advisories document insufficient buffer checks in DM_OP hypercalls, allowing operations to proceed without validating the caller-supplied buffer count. This can enable reading of Xen stack contents and potentially leak dat...

CVE-2026-42494

The CVE-2026-42494 issue affects the libfsimage iso9660 driver where on-disk fields controlled by an attacker are used to derive several lengths without validation. The directory loop assumes a valid record length, making it vulnerable to malformed directory records. Additional problems include p...

CVE-2026-62424

CVE-2026-62424 affects the libfsimage iso9660 driver (Rock Ridge NM record processing). Attacker-controlled on-disk fields derive several lengths without validation, with potential underflow in System Use/Rock Ridge length handling, and specifically NM record processing may rely on a good entry l...

CVE-2026-62423

The provided documents describe CVE-2026-62423 as a vulnerability in libfsimage’s iso9660 driver, where the Rock Ridge extension loop assumes a valid inner record length and derives several lengths from attacker-controlled on-disk fields without validation. This can allow misinterpretation of dir...

buffer overruns in libfsimage iso9660 handling

ISSUE DESCRIPTION The directory and Rock Ridge / SUSP walk in libfsimage's iso9660 driver derives several lengths directly from attacker-controlled on-disk fields without validating them: The directory loop itself assumes a good record length. This is CVE-2026-42494. The calculation of the System...

CVE-2026-55970

A flaw was found in Apache Thrift C++ bindings. This buffer over-read vulnerability allows a remote attacker to read beyond the intended memory boundaries. This could lead to the disclosure of sensitive information or cause the application to become unavailable...

gstreamer1-plugins-good: GStreamer: Heap buffer overflow in WavPack decoder via integer overflow

A flaw was found in GStreamer's WavPack audio decoder in gst-plugins-good. When processing a specially crafted WavPack file, an integer overflow in the buffer size calculation 4 blocksamples channels in gstwavpackdechandleframe causes a very small heap allocation. The WavPack library then writes...

httpd: mod_proxy_ajp: heap-based buffer over-read and memory disclosure in ajp_parse_data()

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the ajpparsedata function attempts to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause a heap-based buffer over-read. This issue potentially lea...
