gnutls: gnutls: Memory corruption due to off-by-one error in PKCS#12 bag handling
A flaw was found in gnutls. An off-by-one error exists in the PKCS12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of...
CVE-2026-58051
libssh2 through 1.11.1 grows its publickey list with SSH2REALLOC but does not zero-initialize new entries before parsing populates them, so a parse failure reaching the cleanup path leaves libssh2publickeylistfree operating on an uninitialized entry. A malicious SSH server offering the publickey...

libssh2 through 1.11.1 grows its publickey list with SSH2REALLOC but does not zero-initialize new entries before parsing populates them, so a parse failure reaching the cleanup path leaves libssh2publickeylistfree operating on an uninitialized entry. A malicious SSH server offering the publickey...
CVE-2026-58050
libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation numattrs sizeoflibssh2publickeyattribute without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer. A malicious S...
Linux Distros Unpatched Vulnerability : CVE-2026-58051
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libssh2 through 1.11.1 grows its publickey list with SSH2REALLOC but does not zero-initialize new entries before parsing populates them, so a parse failure...
