CVE-2026-54417 Integer Overflow in rxi/microtar mtar_next() Causes Infinite Loop DoS

An integer overflow in the mtarnext function in src/microtar.c in rxi microtar 0.1.0 allows a remote attacker to cause a denial of service uncontrolled CPU consumption / infinite loop via a crafted tar archive. mtarnext computes the offset to the next record as rounduph.size, 512 +...

CVE-2026-9150 Libsolv: stack-based buffer overflow in libsolv's debian metadata parser when handling sha384/sha512 checksums

A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption a...

Astra Linux – Vulnerability in openssl1.0

There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...
