OpenEXR has heap-buffer-overflow via signed integer underflow in ImfContextInit.cpp

SummaryA heap-buffer-overflow OOB read occurs in the istreamnonparallelread function in ImfContextInit.cpp when parsing a malformed EXR file through a memory-mapped IStream. A signed integer subtraction produces a negative value that is implicitly converted to sizet, resulting in a massive length...

OpenEXR: Heap information disclosure in PXR24 decompression via unchecked decompressed size (undo_pxr24_impl)

SummaryThe PXR24 decompression function undopxr24impl in OpenEXR internalpxr24.c ignores the actual decompressed size outSize returned by exruncompressbuffer and instead reads from the scratch buffer based solely on the expected size uncompressedsize derived from the header metadata.Additionally,...

PYSEC-2026-2940 PraisonAI Has SSRF in FileTools.download_file() via Unvalidated URL

Summary FileTools.downloadfile in praisonaiagents validates the destination path but performs no validation on the url parameter, passing it directly to httpx.stream with followredirects=True. An attacker who controls the URL can reach any host accessible from the server including cloud metadata...

pypdf: manipulated stream length values can exhaust RAM

ImpactAn attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing a content stream with a rather large /Length value, regardless of the actual data length inside the stream. PatchesThis has been fixed in pypdf==6.8.0. WorkaroundsIf you cannot...

Reverb use after free vulnerability

There exists a use after free vulnerability in Reverb.Reverb supports the VARIANT datatype, which is supposed to represent an arbitrary object in C++. When a tensor proto of type VARIANT is unpacked, memory is first allocated to store the entire tensor, and a ctor is called on each instance...

pypdf and PyPDF2 possible Infinite Loop when a comment isn't followed by a character

ImpactAn attacker who uses this vulnerability can craft a PDF which leads to an infinite loop if parsecontentstream is executed. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. That is, for example, the case if the...
