-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5078-1 security@debian.org https://www.debian.org/security/ Sebastien Delafond February 16, 2022 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : zsh CVE ID : CVE-2021-45444 It was discovered that zsh, a powerful shell and scripting language, did not prevent recursive prompt expansion. This would allow an attacker to execute arbitrary commands into a user's shell, for instance by tricking a vcs_info user into checking out a git branch with a specially crafted name. For the oldstable distribution (buster), this problem has been fixed in version 5.7.1-1+deb10u1. For the stable distribution (bullseye), this problem has been fixed in version 5.8-6+deb11u1. We recommend that you upgrade your zsh packages. For the detailed security status of zsh please refer to its security tracker page at: https://security-tracker.debian.org/tracker/zsh Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEAqSkbVtrXP4xJMh3EL6Jg/PVnWQFAmIM+lsACgkQEL6Jg/PV nWSdbwgAnFfNdi+FHSZ01O4ecnKII5d9/BAZWhEcbKTZY7Yz8h1JyKNoSkm46VG2 BuTdN6sGMtkcZ+0+DmQBfLvfaZ2Eelt6UaaHkwg21XyLabrd+xfEdG++bLg55rGg arUTN+mIRG+L+2UQXMSYoXPSubTPA/ZaR4BIyWQpK+xN+nyG0cm2WKE4OZl/ahnn zdqnhncaJ2l4L4Q4IttK3c1Zhqb/OwMFaad/C45gBb85doNFnImf9iZNa52Mt807 XIXcK+OYPQ82Au4reftBrjAiccGua0emkY2XI0X5Zhu/R/VNTB0MIz9PubOKMNNg SFwWrhmbuO0OY9jI51TvmFG43OHHSg== =mhTR -----END PGP SIGNATURE-----
