Zlib is a general-purpose data compression library developed by Mark Adler in the United States. Zlib versions 3.0.0 and earlier, as well as versions 3.1.0, 3.1.1, 3.2.0, and 3.2.1, contain security vulnerabilities. These vulnerabilities stem from a buffer overflow in Zlib::GzipReader, which may...

PT-2026-33367

Name of the Vulnerable Software and Affected Versions spdystream versions prior to 0.5.1 Description The SPDY/3 frame parser fails to validate attacker-controlled counts and lengths before allocating memory. This occurs in three allocation paths: the SETTINGS frame entry count, the header count i...

zlib: zlib: Memory corruption via buffer overflow in Zlib::GzipReader

A flaw was found in zlib, a Ruby interface for the zlib compression/decompression library. The Zlib::GzipReader component contains a buffer overflow vulnerability. This occurs because the zstreambufferungets function does not ensure sufficient memory capacity before moving existing data, which ca...
