[GLSA-200508-04] Netpbm: Arbitrary code execution in pstopnm |
||
Netpbm: Arbitrary code execution in pstopnm Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200508-04 (Netpbm: Arbitrary code execution in pstopnm) Max Vozeler reported that pstopnm calls the GhostScript interpreter on untrusted PostScript files without specifying the -dSAFER option, to convert a PostScript file into a PBM, PGM, or PNM file. Impact A possible hacker could craft a malicious PostScript file and entice a user to run pstopnm on it, resulting in the execution of arbitrary commands with the permissions of the user running pstopnm. Workaround There is no known workaround at this time.
