Package : phpseclib Version : 1.0.19-3~deb10u3 CVE ID : CVE-2024-27354 CVE-2024-27355

Security issues were discovered in phpseclib, a PHP library for arbitrary-precision integer arithmetic, which could lead to Denial of Service.

CVE-2024-27354

An attacker can construct a malformed certificate containing an extremely large prime to cause a denial of service (CPU consumption for an `isPrime` primality check).

This issue was introduced when attempting to fix CVE-2023-27560.

CVE-2024-27355

When processing the ASN.1 object identifier of a certificate, a sub identifier may be provided that leads to a denial of service (CPU consumption for `decodeOID`).

For Debian 10 buster, these problems have been fixed in version 1.0.19-3~deb10u3.

We recommend that you upgrade your phpseclib packages.

For the detailed security status of phpseclib please refer to its security tracker page at:
