Changelog

nettle (3.5.1+really3.5.1-2ubuntu0.2) focal-security; urgency=medium

  * SECURITY UPDATE: crash in RSA decryption via manipulated ciphertext
    - debian/patches/CVE-2021-3580-1.patch: change _rsa_sec_compute_root_tr
      to take a fixed input size in rsa-decrypt-tr.c, rsa-internal.h,
      rsa-sec-decrypt.c, rsa-sign-tr.c, testsuite/rsa-encrypt-test.c.
    - debian/patches/CVE-2021-3580-2.patch: add input check to rsa_decrypt
      family of functions in rsa-decrypt-tr.c, rsa-decrypt.c,
      rsa-sec-decrypt.c, rsa.h, testsuite/rsa-encrypt-test.c.
    - CVE-2021-3580

libhogweed5: low level cryptographic library (public-key cryptos)

 Nettle is a cryptographic library that is designed to fit easily in more or
 less any context: In crypto toolkits for object-oriented languages (C++,
 Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel
 space.
 .
 It tries to solve a problem of providing a common set of cryptographic
 algorithms for higher-level applications by implementing a
 context-independent set of cryptographic algorithms. In that light, Nettle
 doesn't do any memory allocation or I/O, it simply provides the
 cryptographic algorithms for the application to use in any environment and
 in any way it needs.
 .
 This package contains the asymmetric cryptographic algorithms, which,
 require the GNU multiple precision arithmetic library (libgmp) for
 their large integer computations.

libhogweed5-dbgsym: debug symbols for libhogweed5
libnettle7: low level cryptographic library (symmetric and one-way cryptos)

 Nettle is a cryptographic library that is designed to fit easily in more or
 less any context: In crypto toolkits for object-oriented languages (C++,
 Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel
 space.
 .
 It tries to solve a problem of providing a common set of cryptographic
 algorithms for higher-level applications by implementing a
 context-independent set of cryptographic algorithms. In that light, Nettle
 doesn't do any memory allocation or I/O, it simply provides the
 cryptographic algorithms for the application to use in any environment and
 in any way it needs.
 .
 This package contains the symmetric and one-way cryptographic
 algorithms. To avoid having this package depend on libgmp, the
 asymmetric cryptos reside in a separate library, libhogweed.

nettle-bin: low level cryptographic library (binary tools)

 Nettle is a cryptographic library that is designed to fit easily in more or
 less any context: In crypto toolkits for object-oriented languages (C++,
 Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel
 space.
 .

 doesn't do any memory allocation or I/O, it simply provides the
 cryptographic algorithms for the application to use in any environment and
 in any way it needs.
 .
 This package contains binary utilities that accompany the library:
 .
    - nettle-lfib-stream - generates a pseudo-random stream, using the Knuth
      lfib (non-cryptographic) pseudo-random generator.
    - sexp-conv - conversion tool for handling the different flavours of sexp
      syntax.
    - pkcs1-conv - converts PKCS#1 keys to sexp format.
    - nettle-hash - command-line tool to compute message digests such as SHA-1.
