Gnupg Libksba vulnerabilities

CVE-2022-3515 [CRITICAL] CWE-190 CVE-2022-3515: A vulnerability was found in the Libksba library due to an integer overflow within the CRL parser. T A vulnerability was found in the Libksba library due to an integer overflow within the CRL parser. The vulnerability can be exploited remotely for code execution on the target system by passing specially crafted data to the application, for example, a malicious S/MIME attachment.

CVE-2022-47629 [CRITICAL] CWE-190 CVE-2022-47629: Libksba before 1.6.3 is prone to an integer overflow vulnerability in the CRL signature parser. Libksba before 1.6.3 is prone to an integer overflow vulnerability in the CRL signature parser.

CVE-2016-4356 [HIGH] CWE-119 CVE-2016-4356: The append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.3 allows remote attack The append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.3 allows remote attackers to cause a denial of service (out-of-bounds read) by clearing the high bit of the byte after invalid utf-8 encoded data.

CVE-2016-4353 [HIGH] CWE-20 CVE-2016-4353: ber-decoder.c in Libksba before 1.3.3 does not properly handle decoder stack overflows, which allows ber-decoder.c in Libksba before 1.3.3 does not properly handle decoder stack overflows, which allows remote attackers to cause a denial of service (abort) via crafted BER data.

CVE-2016-4354 [HIGH] CWE-119 CVE-2016-4354: ber-decoder.c in Libksba before 1.3.3 uses an incorrect integer data type, which allows remote attac ber-decoder.c in Libksba before 1.3.3 uses an incorrect integer data type, which allows remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow.

CVE-2016-4574 [HIGH] CVE-2016-4574: Off-by-one error in the append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.4 Off-by-one error in the append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read) via invalid utf-8 encoded data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-4356.

CVE-2016-4579 [HIGH] CWE-20 CVE-2016-4579: Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read and cr Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via unspecified vectors, related to the "returned length of the object from _ksba_ber_parse_tl."

CVE-2016-4355 [HIGH] CWE-119 CVE-2016-4355: Multiple integer overflows in ber-decoder.c in Libksba before 1.3.3 allow remote attackers to cause Multiple integer overflows in ber-decoder.c in Libksba before 1.3.3 allow remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow.

CVE-2014-9087 [HIGH] CWE-191 CVE-2014-9087: Integer underflow in the ksba_oid_to_str function in Libksba before 1.3.2, as used in GnuPG, allows Integer underflow in the ksba_oid_to_str function in Libksba before 1.3.2, as used in GnuPG, allows remote attackers to cause a denial of service (crash) via a crafted OID in a (1) S/MIME message or (2) ECC based OpenPGP data, which triggers a buffer overflow.

CVE-2006-5111 [MEDIUM] CVE-2006-5111: The libksba library 0 The libksba library 0.9.12 and possibly other versions, as used by gpgsm in the newpg package on SUSE LINUX, allows attackers to cause a denial of service (application crash) via a malformed X.509 certificate in a signature.
