Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack in the SharedKey::sign function. An attacker can potentially forge signatures by exploiting differences in processing time during HMAC signature verification. Remediation Upgrade httpsig to version 0.0.19 or higher...

CVE-2025-59058 httpsig-rs's HMAC verification is vulnerable to timing attack

httpsig-rs is a Rust implementation of IETF RFC 9421 http message signatures. Prior to version 0.0.19, the HMAC signature comparison is not timing-safe. This makes anyone who uses HS256 signature verification vulnerable to a timing attack that allows the attacker to forge a signature. Version...

CVE-2025-59058

Affected software: httpsig-rs (Rust implementation of IETF RFC 9421 http message signatures). Vulnerability: Prior to version 0.0.19, HMAC signature comparison is not timing-safe, allowing a timing attack to forge signatures during HS256 verification. Impact (as stated): Attack could forge a sign...

httpsig-rs 安全漏洞

httpsig-rs is a Rust library by Jun Kurihara Personal Developer. A security vulnerability exists in versions prior to httpsig-rs 0.0.19, which stems from an HMAC signature comparison that does not utilize a temporal security approach, which could lead to an attacker forging a signature...

PT-2025-37315

Name of the Vulnerable Software and Affected Versions: httpsig-rs versions prior to 0.0.19 Description: httpsig-rs is a Rust implementation of IETF RFC 9421 http message signatures. The HMAC signature comparison is not timing-safe in versions prior to 0.0.19, potentially allowing an attacker to...

krb5: Kerberos RC4-HMAC-MD5 Checksum Vulnerability Enabling Message Spoofing via MD5 Collisions

A vulnerability in the MIT Kerberos implementation allows GSSAPI-protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption types, an attacker could exploit MD5 collisions to forge message integrity codes. This ma...
