Pillow: NULL pointer dereference in Image.merge via an unvalidated band 0

Summary Image.merge checks the mode of every input band except band 0. If band 0 is a single-band I or F image, the native merge routine reads a pixel pointer that is NULL for those modes and the process crashes. The IPTC plugin reaches this from a plain Image.open followed by a load, and IPTC ha...

Pillow: Invalid free in FreeType glyph rendering when a stroker is active

Summary When text is drawn with a non-zero stroke width, Pillow creates a FreeType stroker and then loads each glyph. If FTLoadGlyph fails for a glyph, the cleanup path calls FTDoneGlyph on the glyph variable. That variable is not initialized before the first measurement loop, and in the render...

virtualenv activate runs commands from the environment name in zsh with PROMPT_SUBST

Impact zsh users activate an environment with the bash activate script, which puts the environment name into PS1. Since 21.13.0 the script escapes backslashes, dollar signs and backticks in that name, but only when BASHVERSION is set, so zsh gets the raw value. With the PROMPTSUBST option set, zs...

virtualenv activate.fish runs commands from a path or prompt with a backslash before a quote

Impact FishActivator defines no quote, so it inherits ViaTemplateActivator.quote, which returns shlex.quotestring. That function follows POSIX sh rules, where a backslash inside single quotes stays a literal character. fish reads ' inside single quotes as an escaped quote and \ as an escaped...

virtualenv activation scripts run code from a path that contains a placeholder name

Impact ViaTemplateActivator.instantiatetemplate replaces the placeholders in an activation template one key at a time, each across the whole text. When a value that it already substituted and quoted contains the name of a later placeholder, the later pass rewrites that name inside the quoted...
