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.
