CVE-2026-44722 pyzipper: Encryption bypass for small files encrypted with pyzipper

pyzipper is a replacement for Python's zipfile that can read and write AES encrypted zip files. Prior to 0.4.0, a Python operator precedence bug in pyzipper/zipfileaes.py caused the AE-2 format to never be automatically selected during encryption, causing encrypted entries to be written in AE-1...

WireGuard Easy through 15.3.0, fixed in commit 66b292b, contains a cryptographically weak one-time link token generation vulnerability that allows unauthenticated network attackers to recover WireGuard peer credentials by brute-forcing a keyspace of at most 1000 candidate tokens per client ID, as...

EulerOS 2.0 SP10 : zlib (EulerOS-SA-2026-2720)

According to the versions of the zlib packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : zlib before 1.3.2 allows CPU consumption via crc32combine64 and crc32combinegen64 because x2nmodp can do right shifts within a loop that has no...

PYSEC-2026-3044 pyzipper has an encryption bypass for small files encrypted using it

Impact A Python operator precedence bug in pyzipper/zipfileaes.py caused the AE-2 format to never be automatically selected during encryption, regardless of file size or compression type. As a result, all encrypted entries are written in AE-1 format unless AE-2 is explicitly forced by the caller...

The vulnerabilities of the functions crc32_combine64 and crc32_combine_gen64 in the open-source data compression library zlib allow attackers to cause service interruptions.

The vulnerability of the crc32combine64 and crc32combinegen64 functions in the open-source data compression library zlib relates to the fact that the x2nmodp function may perform right shifts within a loop without a termination condition. Exploiting this vulnerability could allow an attacker to...
