CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 1CVE-2019-20454 – pcre: Out of bounds read in JIT mode when \X is used in non-UTF mode
https://notcve.org/view.php?id=CVE-2019-20454
An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is JIT compiled and used to match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may be vulnerable to this flaw, which would allow an attacker to crash the application. The flaw occurs in do_extuni_no_utf in pcre2_jit_compile.c. Se detectó una lectura fuera de límites en PCRE versiones anteriores a 10.34, cuando el patrón \X es compilado en JIT y usado para hacer coincidir temas especialmente diseñados en modo no UTF. Las aplicaciones que utilizan PCRE para analizar entradas no confiables pueden ser vulnerables a este fallo, lo que permitiría a un atacante bloquear la aplicación. • https://bugs.exim.org/show_bug.cgi?id=2421 https://bugs.php.net/bug.php?id=78338 https://bugzilla.redhat.com/show_bug.cgi?id=1735494 https://lists.debian.org/debian-lts-announce/2023/03/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OQRAHYHLRNMBTPR3KXVM27NSZP3KTOPI https://security.gentoo.org/glsa/202006-16 https://vcs.pcre.org/pcre2?view=revision&revision=1092 https://access.redhat.com/security/cve/CVE-2019-20454 • CWE-125: Out-of-bounds Read •
