  script_tag(name:"insight", value:"This update for mbedtls fixes the following issues:

  - Update to version 2.28.7:

  - Resolves CVE-2024-23170 boo#1219336

  - Update to 2.28.6:

       Changes:

  * Mbed TLS is now released under a dual Apache-2.0 OR GPL-2.0-or-later
         license. Users may choose which license they take the code under.

  - Update to 2.28.5:

       Features:

  * The documentation of mbedtls_ecp_group now describes the optimized
         representation of A for some curves. Fixes gh#Mbed-TLS/mbedtls#8045.

       Security:

  * Developers using mbedtls_pkcs5_pbes2() or mbedtls_pkcs12_pbe() should
         review the size of the output buffer passed to this function, and note
         that the output after decryption may include CBC padding. Consider
         moving to the new functions mbedtls_pkcs5_pbes2_ext() or
         mbedtls_pkcs12_pbe_ext() which checks for overflow of the output
         buffer and reports the actual length of the output.

  * Improve padding calculations in CBC decryption, NIST key unwrapping
         and RSA OAEP decryption. With the previous implementation, some
         compilers (notably recent versions of Clang and IAR) could produce
         non-constant time code, which could allow a padding oracle attack if
         the attacker has access to precise timing measurements.

  * Fix a buffer overread when parsing short TLS application data records
         in ARC4 or null-cipher cipher suites. Credit to OSS-Fuzz.

       Bugfix:

  * Fix x509 certificate generation to conform to RFC 5480 / RFC 5758 when
         using ECC key. The certificate was rejected by some crypto frameworks.
         Fixes gh#Mbed-TLS/mbedtls#2924.

  * Fix some cases where mbedtls_mpi_mod_exp, RSA key construction or
         ECDSA signature can silently return an incorrect result in low memory
         conditions.

  * Fix IAR compiler warnings. Fixes gh#Mbed-TLS/mbedtls#7873,
         gh#Mbed-TLS/mbedtls#4300.

  * Fix an issue when parsing an otherName subject alternative name into a
         mbedtls_x509_san_other_name struct. The type-id of the otherName was
         not copied to the struct. This meant that the struct had incomplete
         information about the otherName SAN and contained uninitialized memory.

  * Fix the detection of HardwareModuleName otherName SANs. These were
         being detected by comparing the wrong field and the check was
         erroneously inverted.

  * Fix an error when MBEDTLS_ECDSA_SIGN_ALT is defined but not
         MBEDTLS_ECDSA_VERIFY_ALT, causing ecdsa verify to fa ...
