VUL-0: CVE-2023-5678: openssl: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow
Last modified: 2024-02-05 09:30:04 UTC
Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(), DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks (as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an excessively large P, it doesn't check for an excessively large Q. An application that calls DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack. DH_generate_key() and DH_check_pub_key() are also called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_pub_key_ex(), EVP_PKEY_public_check(), and EVP_PKEY_generate(). Also vulnerable are the OpenSSL pkey command line application when using the "-pubcheck" option, as well as the OpenSSL genpkey command line application. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.

can you please submit fixed packages?
All codestreams were affected so it took me some time to backport/fix it. Most codestreams were submitted today. I will share a list of submissions once everything is done.
All affected codestreams fixed, assigning back to security team. > Codestream Package Request > ------------------------------------------------------------------------------------ > SUSE:SLE-15-SP5:Update openssl-3 https://build.suse.de/request/show/312744 > SUSE:SLE-15-SP4:Update openssl-3 https://build.suse.de/request/show/312748 > SUSE:ALP:Source:Std:1.0 openssl-3 https://build.suse.de/request/show/312870 > openSUSE:Factory openssl-3 https://build.opensuse.org/request/show/1126784 > ------------------------------------------------------------------------------------ > SUSE:SLE-15-SP5:Update openssl-1_1 https://build.suse.de/request/show/312750 > SUSE:SLE-15-SP4:Update openssl-1_1 https://build.suse.de/request/show/312789 > SUSE:SLE-15-SP2:Update openssl-1_1 https://build.suse.de/request/show/312773 > SUSE:SLE-15-SP1:Update openssl-1_1 https://build.suse.de/request/show/312774 > SUSE:SLE-12-SP4:Update openssl-1_1 https://build.suse.de/request/show/312777 > SUSE:ALP:Source:Std:1.0 openssl-1_1 https://build.suse.de/request/show/312871 > openSUSE:Factory openssl-1_1 https://build.opensuse.org/request/show/1126787 > ------------------------------------------------------------------------------------ > SUSE:SLE-15:Update openssl-1_0_0 https://build.suse.de/request/show/312779 > SUSE:SLE-12-SP4:Update openssl-1_0_0 https://build.suse.de/request/show/312782 > SUSE:SLE-11-SP3:Update openssl1 https://build.suse.de/request/show/312784 > openSUSE:Factory openssl-1_0_0 https://build.opensuse.org/request/show/1126788 > ------------------------------------------------------------------------------------ > SUSE:SLE-12:Update compat-openssl098 https://build.suse.de/request/show/312785 > SUSE:SLE-11-SP1:Update openssl https://build.suse.de/request/show/312788
