xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in font alias resolution due to libXfont2 name length mismatch

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB key types due to unchecked shift levels

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel XkbNumKbdGroups but CheckKeyTypes does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift...

Medium: perl-Storable

Issue Overview: Storable versions before 3.05 for Perl has a stack overflow. The retrievehook function stored the length of the class name into a signed integer but in read operations treated the length as unsigned. This allowed an attacker to craft data that could trigger the overflow...

The version of ImageMagick installed on the remote host is prior to 6.9.10.97-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3373 advisory. ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions...

Important: perl-CryptX

Issue Overview: CryptX versions before 0.088001 for Perl compare AEAD authentication tags in non-constant time in the streaming decryptdone path. The decryptdone$tag form compares it against the computed tag with memNE memcmp != 0, which short-circuits on the first differing byte, so its run time...
