MySQL Authentication Bypass Vulnerability CVE-2012-2122 When connecting to MariaDB/MySQL, the entered password is compared with the expected correct password. Due to improper handling, even if memcmp returns a non-zero value, MySQL may still consider the two passwords as identical. That is, as lo...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: mtd: Avoid boot crashes in the RedBoot partition table parser Given the CONFIGFORTIFYSOURCE=y setting and a recent compiler version, the commit 439a1bcac648 “fortify: Use builtindynamicobjectsize when available” results in the...
Astra Linux – Vulnerability in Heimdal
The fix for CVE-2022-3437 involved changing the memcmp function to run in constant time, as well as providing a workaround for a compiler bug by adding comparisons of the result with the value “!= 0” to the memcmp function. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0...
AZL-96971 CVE-2026-53583 affecting package libgit2 1.7.2-1
libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Prior to 1.8.6 and 1.9.5, verifyservercert in src/libgit2/streams/openssl.c uses an inverted !!memcmp result in the GENIPADD...
CVE-2026-53583
In libgit2 before 1.8.6 and 1.9.5, verify_server_cert in src/libgit2/streams/openssl.c uses an inverted !!memcmp in the GEN_IPADD branch, so OpenSSL builds accept mismatched IP SubjectAltName certificates and reject matching ones, enabling a network attacker to intercept IP-literal HTTPS connecti...
glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend"
A flaw was found in GLib. A buffer over-read can occur in giochannelreadlinebackend in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes ...
