zlib Heap Buffer Overflow DoS

The vulnerability of the zstreambufferungets function in the zlib library is related to the copying of buffers without checking the size of the input data. Exploiting this vulnerability could allow an attacker to cause memory corruption remotely...

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...

GHSA-G857-HHFV-J68W Buffer Overflow in Zlib::GzipReader ungetc via large input leads to memory corruption

Details A buffer overflow vulnerability exists in Zlib::GzipReader. The zstreambufferungets function prepends caller-provided bytes ahead of previously produced output but fails to guarantee the backing Ruby string has enough capacity before the memmove shifts the existing data. This can lead to...

DEBIAN-CVE-2026-27820

zlib is a Ruby interface for the zlib compression/decompression library. Versions 3.0.0 and below, 3.1.0, 3.1.1, 3.2.0 and 3.2.1 contain a buffer overflow vulnerability in the Zlib::GzipReader. The zstreambufferungets function prepends caller-provided bytes ahead of previously produced output but...

Buffer Overflow

Overview Affected versions of this package are vulnerable to Buffer Overflow via the zstreambufferungets function. An attacker can cause memory corruption by providing input that causes the buffer length to exceed its capacity, leading to a buffer overflow during memory operations. Remediation...
