CVSS: 9.8EPSS: 1%CPEs: 5EXPL: 2CVE-2022-3515 – GnuPG libksba CRL File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2022-3515
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. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GnuPG libksba. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of CRL files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. • https://access.redhat.com/security/cve/CVE-2022-3515 https://bugzilla.redhat.com/show_bug.cgi?id=2135610 https://dev.gnupg.org/rK4b7d9cd4a018898d7714ce06f3faf2626c14582b https://security.netapp.com/advisory/ntap-20230706-0008 https://www.gnupg.org/blog/20221017-pepe-left-the-ksba.html • CWE-190: Integer Overflow or Wraparound •

A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory. Una vulnerabilidad de "escritura en pila" en GnuPG (gpg) 1.x anterior a la 1.4.6, 2.x anterior a la 2.0.2 y 1.9.0 hasta la 1.9.95 permite a atacantes ejecutar código de su elección mediante paquetes OpenPGP artesanales que provocan que GnuPG haga referencia a un puntero a función que está en memoria (en la pila) que ya ha sido liberada. • ftp://patches.sgi.com/support/free/security/advisories/20061201-01-P.asc http://lists.gnupg.org/pipermail/gnupg-announce/2006q4/000491.html http://lists.suse.com/archive/suse-security-announce/2006-Dec/0004.html http://secunia.com/advisories/23245 http://secunia.com/advisories/23250 http://secunia.com/advisories/23255 http://secunia.com/advisories/23259 http://secunia.com/advisories/23269 http://secunia.com/advisories/23284 http://secunia.com/advisories/23290 http://secunia. •
