CVE-2026-102555Libsoup: libsoup: heap buffer overflow via uninitialized length in data-uri base64 decoding

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterpr… Yayım: (1 ay önce)

Açıklama

A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted data URI.

Zayıflık türü (CWE): CWE-125

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.

Abrt: abrt: abrt-server trusts client-supplied pid= allowing unprivileged read of other processes' /proc environ

Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8

A flaw was found in abrt. abrt-server trusts a client-supplied PID when creating problem dumps over abrt.socket and, running as root, copies that process's /proc data (including environ) into a dump directory owned by the connecting unprivileged user. This al…

Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8

A flaw was found in abrt. The completeness check introduced to mitigate CVE-2026-54228 and CVE-2026-54229 only verifies that a dump directory contains a "count" element, which an unprivileged user can create. This allows a local attacker to bypass the guard a…
